"A segfault in the segfault handler" occurs also on my x86_64-linux and aarch64-linux when `gcc-10.2.0 -gdwarf-5` is used. A backtrace with GDB:

So is it really due to DWARF5? Why is that just on two platforms?

Issue #17585 has been updated by xtkoba (Tee KOBAYASHI).
File ruby-addr2line-dwarf5.patch added
A patch is attached to avoid segfaults with DWARF5.
In summary, there are two changes: (1) skip DW_FORM_implicit_const attributes properly, and (2) skip DIEs which have DW_AT_entry_pc attributes. Here, (2) is just a workaround and it would be desirable if we could properly interpret the attributes.
The workaround which I posted before is no longer needed.

So is it really due to DWARF5? Why is that just on two platforms?

Issue #17585 has been updated by xtkoba (Tee KOBAYASHI).
File ruby-dwarf5-debug_line.patch added
It seems that GCC emits version 3 `.debug_line` sections even when `-gdwarf-5` is provided, in contrast to Clang/LLVM emitting version 5, which `addr2line.c` simply skips currently.
Not causing crashes with DWARF-5 is one thing, and supporting DWARF-5 is another. It will require a fair amount of work to fully support version 5 `.debug_line` (or other) sections.
I tried making a minimal modification to `addr2line.c` so that it prints file:line infomation with Clang/LLVM's DWARF-5 sections. A patch is attached for that. It works with my x86_64 Linux + Clang 11.0.1, but probably will not with others.

Fedora recently switched from DWARF4 to DWARF5 and since that time, I observe test suite errors on ppc64le:

So is it really due to DWARF5? Why is that just on two platforms?

Issue #17585 has been updated by xtkoba (Tee KOBAYASHI).
Excuse me, but the patch in #note-6 is just a scratch and is not expected to work as it is.
And it is highly probable that there exists new attributes from DWARF-5 that are not covered by the patch in #note-5.
Once I thought it would be a workaround to add `-gdwarf-4` to `debugflags`, but it will be insufficient and will still cause a crash when a shared library linked from ruby (e.g. libc.so) uses DWARF-5.
Now might be the time to consider moving from Ruby's own addr2line to Ian Lance Taylor's libbacktrace:

Fedora recently switched from DWARF4 to DWARF5 and since that time, I observe test suite errors on ppc64le:

So is it really due to DWARF5? Why is that just on two platforms?

Issue #17585 has been updated by xtkoba (Tee KOBAYASHI).
For the libbacktrace library, I made a feature request (Feature #17638).
What I feel strange is that the failures were reported to happen only on two platforms, contrary to my experiment in which a crash occurred with x86_64-linux + `gcc-10.2.0 -gdwarf-5 -ggdb3`.
It might not be improbable that in the reported situations crashes happened within backtrace(3). I know that it can cause a crash on QEMU-user-emulated ppc64le Linux. It is true that if so the version of DWARF would be irrelevant, but it might be worth investigating using GDB or so exactly where a crash happens.

Issue #17585 has been updated by xtkoba (Tee KOBAYASHI).
File ruby-dwarf5-avoid_crash-r1.patch added
A (revised) patch is attached to avoid segfaults with GCC's DWARF 5.
In summary, there are three changes:
(1) correct the interpretation of `DW_LNS_advance_pc` statements when the minimum instruction length is not equal to 1 (which is the case for aarch64, arm and powerpc64le),
(2) skip `DW_FORM_implicit_const` attributes properly, and
(3) read and use the `.debug_rnglists` section if available.
When applied together with the patch for Bug #17656, this patch will make `addr2line.c` correctly extract `function+offset` and `file:line` information from GCC's DWARF 5 sections, except that some "inlined by" information is not shown.
Note that in the above changes, (3) is minimal and only `DW_RLE_base_address` and `DW_RLE_offset_pair` are interpreted, because other range list entries seem unnecessary for now. It is highly probable that other entries become necessary in the future.
I hope that the workaround in #note-3 would be no longer needed.
#note-5 is deleted to avoid confusion.

So is it really due to DWARF5? Why is that just on two platforms?

I have tested this patch (without any others you have referenced) and after 10 build in Fedora build system (that is 60 builds on various platforms supported by Fedora) and it seems to fix the original issue. I think I'll keep it applied in Fedora, unless you foresee some further issues.
Thx a lot for working on this!

Issue #17585 has been updated by xtkoba (Tee KOBAYASHI).
Glad to hear that :-)
What I am still (probably too) anxious about is that the current `addr2line.c` calls a lot of async-signal unsafe functions in it. It is true that practically they seem to cause no problem 99% of the time. But theoretically any chaos can happen as long as these functions are used.

Issue #17585 has been updated by vo.x (Vit Ondruch).
Backport changed from 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN to 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: REQUIRED
Setting the backport flag, because it would be useful for Fedora/RHEL and we could drop one patch from our package. However, I understand this might be considered as a new feature and therefore not backported.

So is it really due to DWARF5? Why is that just on two platforms?

Issue #17585 has been updated by xtkoba (Tee KOBAYASHI).
GCC 11 is released yesterday, and in [Changes, New Features, and Fixes](https://gcc.gnu.org/gcc-11/changes.html) it is said that:
```
To take full advantage of DWARF version 5 GCC needs to be build against binutils version 2.35.2 or higher. When GCC is build against earlier versions of binutils GCC will still emit DWARF version 5 for most debuginfo data, but will generate version 4 debug line tables (even when explicitly given `-gdwarf-5`).
```
Though I have not yet tested the released version of GCC 11, there will be (at least) three cases according to the version of GCC and binutils when GCC is supplied with the `-gdwarf-5` option (which is the default for GCC 11).
1. GCC 10 (+ binutils with any version?): version 5 `.debug_info`, **version 3** `.debug_line` (as noted in #note-6)
* This case is what I aimed at in the main issue.
2. GCC 11 + binutils with version >= 2.35.2: version 5 `.debug_info`, **version 5** `.debug_line`
* As I wrote in #note-6, version 5 `.debug_line` is just skipped in the current `addr2line.c`, and so I suppose there will be no new issue in this case other than that `filename:lineno` information is not shown in C backtrace.
3. GCC 11 + binutils with version < 2.35.2: version 5 `.debug_info`, **version <= 4** `.debug_line`
* The binutils in my environment is up to date, and so I will not be able to test this case. Hopefully the same as case 1.
To summarize, I hope there will be no new issue with the released version of GCC 11. Anyway, feel free to reopen this ticket whenever a segfault is observed in `addr2line.c` with DWARF 5.

Issue #17585 has been updated by vo.x (Vit Ondruch).
Fedora Rawhide is using GCC11 since ~beginning of the year and I am not aware of any issues. Actually, Fedora 34 was released yesterday, so should there been any issues, we will soon find out :)

Issue #17585 has been updated by nagachika (Tomoyuki Chikanaga).
