Bug #80443 [Fbk]: sysvsem segfault

Edit report at https://bugs.php.net/bug.php?id=80443&edit=1 ID: 80443 Updated by: nikic@php.net Reported by: video dot ice dot power at seznam dot cz Summary: sysvsem segfault Status: Feedback Type: Bug Package: Semaphore related Operating System: Linux/docker-alpine PHP Version: 8.0.0 Block user comment: N Private report: N New Comment: I was able to reproduce *a* segfault with JIT enabled on an older build, but no longer on current 8.0 HEAD. So most likely this issue is already resolved, though of course it could be another unrelated segfault.
