ruby: 3.2.2 async: 2.5.0 debug 1.7.2

Does it work without the debug gem?

[pbstriker38]

Yes

[ioquatix]

I believe the debug gem is incompatible with fibers, do you mind filing a bug report with them and linking it to this issue?

[pbstriker38]

ok. I can do that

[pbstriker38]

Looks like it's already an open issue

Thanks for your report.

The fix is here: https://github.com/ruby/debug/pull/987

This issue cannot be fixed by the async gem.

So I will close it.
