Issue #18250 has been updated by nobu (Nobuyoshi Nakada).
That is not enough.
```
$ ./ruby -v -e 'def foo((x, y)) -> {super}; end' -e 'Ractor.make_shareable(foo(nil))'

Bug #18250: Anonymous variables seem to break `Ractor.make_shareable`
https://bugs.ruby-lang.org/issues/18250#change-94117
* Author: tenderlovemaking (Aaron Patterson)
* Status: Open
* Priority: Normal
* ruby -v: ruby 3.0.1p64 (2021-04-05 revision 0fb782ee38) [x86_64-darwin20]
* Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN
----------------------------------------
The following code breaks with a strange error:
```ruby
def foo(*); ->{ super };end
Ractor.make_shareable(foo) # expected Symbol
```
Output:
```
[aaron@tc ~/g/ruby (master)]$ cat test.rb
def foo(*); ->{ super };end
Ractor.make_shareable(foo) # expected Symbol
[aaron@tc ~/g/ruby (master)]$ ruby test.rb
<internal:ractor>:816:in `make_shareable': wrong argument type false (expected Symbol) (TypeError)
from test.rb:2:in `<main>'
[aaron@tc ~/g/ruby (master)]$
```
The reason is because the `*` parameter has no name, but Ractor tries to find the name so it can make an exception.
I *expect* the above program to raise an `Ractor::IsolationError`, but instead it raises a `TypeError`.
I've attached a patch that fixes this bug.

Issue #18250 has been updated by byroot (Jean Boussier).
So following the last fixes Rails CI, as well as Shopify CI with regular ruby-head now passes.
However I noticed our ruby-head debug builds are running into an assertion error:
```
id_table.c:153: hash_table_raw_insert: Assertion 'key != 0' failed.
```
I replaced the `assert` with `rb_bug` to get a proper crash report:
```
/tmp/bundle/ruby/3.1.0/gems/bootsnap-1.9.1/lib/bootsnap/compile_cache/iseq.rb:19: [BUG] hash_table_raw_insert key = 0

Bug #18250: Anonymous variables seem to break `Ractor.make_shareable`
https://bugs.ruby-lang.org/issues/18250#change-94628
* Author: tenderlovemaking (Aaron Patterson)
* Status: Open
* Priority: Normal
* ruby -v: ruby 3.0.1p64 (2021-04-05 revision 0fb782ee38) [x86_64-darwin20]
* Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN
----------------------------------------
The following code breaks with a strange error:
```ruby
def foo(*); ->{ super };end
Ractor.make_shareable(foo) # expected Symbol
```
Output:
```
[aaron@tc ~/g/ruby (master)]$ cat test.rb
def foo(*); ->{ super };end
Ractor.make_shareable(foo) # expected Symbol
[aaron@tc ~/g/ruby (master)]$ ruby test.rb
<internal:ractor>:816:in `make_shareable': wrong argument type false (expected Symbol) (TypeError)
from test.rb:2:in `<main>'
[aaron@tc ~/g/ruby (master)]$
```
The reason is because the `*` parameter has no name, but Ractor tries to find the name so it can make an exception.
I *expect* the above program to raise an `Ractor::IsolationError`, but instead it raises a `TypeError`.
I've attached a patch that fixes this bug.

@nobu the Shopify "monolith". I didn't have time to reduce it just yet, I'll hopefully have a smaller repro this week.

Issue #18250 has been updated by byroot (Jean Boussier).
I reduced it to a small script:
```ruby
iseq = RubyVM::InstructionSequence.compile(<<~RUBY)
def transport_request(req, *)
foo do
super
end
end
RUBY
RubyVM::InstructionSequence.load_from_binary(iseq.to_binary)
```
Seems very similar to the original error.

Issue #18250 has been updated by byroot (Jean Boussier).
It's very weird, `def transport_request(req, *)` fail the assertion, but `def transport_request(a, *)` doesn't. Maybe because `req` legitimately hash to `0`?

This bug made it to the recently released ruby 3.0.3: https://github.com/Shopify/bootsnap/issues/378#issuecomment-977949971
Seems like the fix wasn't backported.

/Users/byroot/src/github.com/Shopify/ruby/test/ruby/test_iseq.rb:1: [BUG] see above.
```
From this test:
```ruby
def test_cdhash_after_roundtrip
# CDHASH was not built properly when loading from binary and
# was causing opt_case_dispatch to clobber its stack canary
# for its "leaf" instruction attribute.
iseq = compile(<<~EOF)
case Class.new(String).new("foo")
when "foo"
42
end
EOF
assert_equal(42, ISeq.load_from_binary(iseq.to_binary).eval)
end
```
That test was added in 4323fa96c4350ecad5f3d607805b7ecd3870bdb5, so I wonder if we miss something.

Bug #18250: Anonymous variables seem to break `Ractor.make_shareable`
https://bugs.ruby-lang.org/issues/18250#change-94917
* Author: tenderlovemaking (Aaron Patterson)
* Status: Closed
* Priority: Normal
* ruby -v: ruby 3.0.1p64 (2021-04-05 revision 0fb782ee38) [x86_64-darwin20]
* Backport: 2.7: DONTNEED, 3.0: REQUIRED
----------------------------------------
The following code breaks with a strange error:
```ruby
def foo(*); ->{ super };end
Ractor.make_shareable(foo) # expected Symbol
```
Output:
```
[aaron@tc ~/g/ruby (master)]$ cat test.rb
def foo(*); ->{ super };end
Ractor.make_shareable(foo) # expected Symbol
[aaron@tc ~/g/ruby (master)]$ ruby test.rb
<internal:ractor>:816:in `make_shareable': wrong argument type false (expected Symbol) (TypeError)
from test.rb:2:in `<main>'
[aaron@tc ~/g/ruby (master)]$
```
The reason is because the `*` parameter has no name, but Ractor tries to find the name so it can make an exception.
I *expect* the above program to raise an `Ractor::IsolationError`, but instead it raises a `TypeError`.
I've attached a patch that fixes this bug.
