https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D206396 Bug ID: 206396 Summary: Crash while concurrent POSIX semaphore access Product: Base System Version: 10.2-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: xelfium@gmail.com CC: freebsd-amd64@FreeBSD.org CC: freebsd-amd64@FreeBSD.org Created attachment 165809 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D165809&action= =3Dedit Test code I have faced a strange issue with POSIX semaphores. Program crashes when several threads concurrently access POSIX semaphore under the same name. I attached a test code to illustrate it. I have tried to compile this code us= ing Clang and GCC but it was the same result. If you add a pause between threads creation then it executes fine. The same code works fine on Linux and latest DragonFlyBSD. --=20 You are receiving this mail because: You are on the CC list for the bug.=
