Bug #17289: Time#strftime occurs Segmentation Fault on ruby-2.7.2p137
https://bugs.ruby-lang.org/issues/17289
* Author: joker1007 (Tomohiro Hashidate)
* Status: Open
* Priority: Normal
* ruby -v: ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x86_64-linux]
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN
----------------------------------------
Segmentation Fault occurred when I run Time#strftime via Time#iso8601 on ruby-2.7.2.
It occurs repeatedly about once a day in our system.
Because it was not possible to make a reproduction case in a simple environment, I share the C Level backtrace and the control frame information at the time of occurrence.
Also, I used strptime gem (https://github.com/nurse/strptime) to create the Time object.
Ruby version: ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x86_64-linux]

Issue #17289 has been updated by joker1007 (Tomohiro Hashidate).
Additional Information:
* I used to use v2.6.2 and Segmentation fault does not occur at that time.
* This stacktrace is reproducible. whenever this error occurs the stacktrace is the same.

----------------------------------------
Segmentation Fault occurred when I run Time#strftime via Time#iso8601 on ruby-2.7.2.
It occurs repeatedly about once a day in our system.
Because it was not possible to make a reproduction case in a simple environment, I share the C Level backtrace and the control frame information at the time of occurrence.
Also, I used strptime gem (https://github.com/nurse/strptime) to create the Time object.

Issue #17289 has been updated by mame (Yusuke Endoh).
Assignee set to shyouhei (Shyouhei Urabe)
Status changed from Open to Assigned
@shyouhei I suspect if this is due to 2.7's new method cache. Could you check it out?
```
/opt/ruby/lib/libruby.so.2.7(timew_out_of_timet_range+0x1c) [0x7fc1188c2ef4] time.c:1664
```
```
1664 if (lt(timexv, mulv(INT2FIX(TIME_SCALE), TIMET2NUM(TIMET_MIN))) ||
```
This line calls `mulv` with two arguments. The first is a FIXNUM and the second is a BIGNUM.
```
108 static VALUE
109 mulv(VALUE x, VALUE y)
110 {
111 if (FIXNUM_P(x) && FIXNUM_P(y)) {
112 return rb_fix_mul_fix(x, y);
113 }
114 if (RB_TYPE_P(x, T_BIGNUM))
115 return rb_big_mul(x, y);
116 return rb_funcall(x, '*', 1, y);
117 }
```
This falls back to `rb_funcall`. This `rb_funcall` is replaced with `rb_funcallv_with_cc`, which seems to invoke `rb_rational_mul`.
```

Bug #17289: Time#strftime occurs Segmentation Fault on ruby-2.7.2p137
https://bugs.ruby-lang.org/issues/17289#change-88238
* Author: joker1007 (Tomohiro Hashidate)
* Status: Assigned
* Priority: Normal
* Assignee: shyouhei (Shyouhei Urabe)
* ruby -v: ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x86_64-linux]
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN
----------------------------------------
Segmentation Fault occurred when I run Time#strftime via Time#iso8601 on ruby-2.7.2.
It occurs repeatedly about once a day in our system.
Because it was not possible to make a reproduction case in a simple environment, I share the C Level backtrace and the control frame information at the time of occurrence.
Also, I used strptime gem (https://github.com/nurse/strptime) to create the Time object.

Issue #17289 has been updated by shyouhei (Shyouhei Urabe).
Looking at it. Though I cannot reproduce this either.

(Nit) This should call Fixnum's mul, not plus.

----------------------------------------
Segmentation Fault occurred when I run Time#strftime via Time#iso8601 on ruby-2.7.2.
It occurs repeatedly about once a day in our system.
Because it was not possible to make a reproduction case in a simple environment, I share the C Level backtrace and the control frame information at the time of occurrence.
Also, I used strptime gem (https://github.com/nurse/strptime) to create the Time object.

Issue #17289 has been updated by shyouhei (Shyouhei Urabe).
Let me tell you that I currently have no idea what is going on. If `rb_funcall` is broken the situation must be more catastrophic than what is reported here (happens once a day).

----------------------------------------
Segmentation Fault occurred when I run Time#strftime via Time#iso8601 on ruby-2.7.2.
It occurs repeatedly about once a day in our system.
Because it was not possible to make a reproduction case in a simple environment, I share the C Level backtrace and the control frame information at the time of occurrence.
Also, I used strptime gem (https://github.com/nurse/strptime) to create the Time object.

Issue #17289 has been updated by joker1007 (Tomohiro Hashidate).
FYI:
I downgraded ruby to v2.7.1.
But in our environment, this error occurred with the same stacktrace.

Segmentation Fault occurred when I run Time#strftime via Time#iso8601 on ruby-2.7.2.
It occurs repeatedly about once a day in our system.
Because it was not possible to make a reproduction case in a simple environment, I share the C Level backtrace and the control frame information at the time of occurrence.
Also, I used strptime gem (https://github.com/nurse/strptime) to create the Time object.

Issue #17289 has been updated by jeremyevans0 (Jeremy Evans).
Status changed from Assigned to Feedback
@joker1007 Can you reproduce this issue with Ruby 3.2 or the master branch? Can you reproduce this issue without the strptime gem?

Bug #17289: Time#strftime occurs Segmentation Fault on ruby-2.7.2p137
https://bugs.ruby-lang.org/issues/17289#change-104288
* Author: joker1007 (Tomohiro Hashidate)
* Status: Feedback

* ruby -v: ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x86_64-linux]
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: REQUIRED
----------------------------------------
Segmentation Fault occurred when I run Time#strftime via Time#iso8601 on ruby-2.7.2.
It occurs repeatedly about once a day in our system.
Because it was not possible to make a reproduction case in a simple environment, I share the C Level backtrace and the control frame information at the time of occurrence.
Also, I used strptime gem (https://github.com/nurse/strptime) to create the Time object.
