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
