[ruby-core:87531] [Ruby trunk Bug#14464] MJIT & MinGW / gcc 7.3.0 seemed ok as of 62337, fail or skip after

Issue #14464 has been updated by k0kubun (Takashi Kokubun).


New issue would be helpful since it seems to be a different problem. And if possible, please minimize the reproductive code. A bug report with reproductive steps using EventMachine might help, but it would be more helpful if you were able to omit EventMachine code to reproduce the SEGV and used very few lines of code.

----------------------------------------
First of all, a thank you to those working on MJIT.

At least three builds of ruby-loco MinGW passed the MJIT tests (62327, 62331, 62337), but after that, the tests have either failed or skipped.  First fail was at 62341.

The most recent build (2018-02-11 trunk 62371), skipped with no timeout error in `jit_supported?`  I haven't looked at patching `test_jit.rb` to see if I can get more info.

I don't know if this is a MinGW issue or a gcc 7.3.0 issue, but, given that it did work for a few builds, I would appreciate it if someone could look into it.  Anything I can help with, I'm happy to.

Thanks, Greg
