Description
This test SEGVs during GC in the loom repo with a linux-x64 release build. Doesn't duplicate for me with a fastdebug build or on other platforms. We seem to have picked up this issue at jdk-16+2 (no sightings when loom was at jdk-16+1).
Comments
The loom repo is now sync'ed up to jdk-16+8 so we've picked up the change for JDK-8249192. I've run the test with --repeat 50 on all platforms and no sighting so I think we can close this issue. Thanks Dean, you were right.

If the problem goes away after JDK-8249192 is fixed, then it's probably the same bug.

Thanks for the links. I did find those but they both seem to be with Graal so I assumed would be a different issue. The test seems to failing consistent on linux-x64 and intermittently on macOS in the CI right now, only the loom repo since jdk-16+1 so might be that the changes in loom are enough to reproduce it a bit more frequently (but only release builds, I haven't seen a failure with a debug build).

This might not be related to loom. See also JDK-8248013 and JDK-8239387, which have crashes with the same test and -Xcomp. It happens about 1% of the time, so that could explain why you haven't seen it before.
