Subject: [ruby-core:111609] [Ruby master Bug#19299] YJIT panicked while holding VM lock acquired at ./yjit/src/core.rs:1693. Aborting...

Issue #19299 has been updated by alanwu (Alan Wu).


Thank you for the report! I was able to reproduce the issue
with the logs you posted, so no worries about reducing your app.

It happens with `yield` and a block with a lot of local variables
and it should be specific to ARM:

```ruby
def foo
  yield
end


30.times do
  foo do
    a1=a2=a3=a4=a5=a6=a7=a8=a9=a10=a11=a12=a13=a14=a15=a16=a17=a18=a19=a20=a21=a22=a23=a24=a25=a26=a27=a28=a29=a30 = 0
  end
end
```

I submitted a [PR](https://github.com/ruby/ruby/pull/7059) to fix this issue.

Bug #19299: YJIT panicked while holding VM lock acquired at ./yjit/src/core.rs:1693. Aborting...
https://bugs.ruby-lang.org/issues/19299#change-100978

* Author: ollym (Oliver Morgan)
* Status: Open
* Priority: Normal
* ruby -v: ruby 3.2.0 (2022-12-25 revision a528908271) +YJIT [arm64-darwin22]
* Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN
----------------------------------------
Attached is the backtrace.

The code is a moderately complex view with partials and translations. The panic happens specifically when i call a translation `t('...')` but if i simplify the view code around that call the panic goes away. I'm trying to create a simplified way to recreate it without giving you the full application.

I'll keep trying, unless the backtrace is enough.
