Jan Beich <jbeich@FreeBSD.org> has reassigned Bugzilla Automation <bugzilla@FreeBSD.org>'s request for maintainer-feedback to x11@FreeBSD.org: Bug 220767: lang/beignet: hangs if not linked against libpthread after jemalloc 5.0.0 update https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=220767 --- Description --- After base r319971 some applications not already linked against threading library started to hang in [umtxn] state. It affects at least Beignet. However, bisecting jemalloc as part of libc requires 8 steps of rebasing FreeBSD-specific changes. Maybe someone can suggest more apps to try that can trigger the issue. $ pkg install clinfo beignet # requires bug 217635 $ LD_PRELOAD=/lib/libthr.so.3 clinfo # works fine $ gdb clinfo (gdb) r
