A X11 based program works fine on 11 and all previous FreeBSD release and L=
inux.When build on FreeBSD-12.0-CURRENT-amd64-20170316-r315413, it gets wei=
rd crashes on either alloc and free.Both cases seem related to _pthread_mut=
ex_init_calloc_cb ().Is this a known issue?=20
Is possible to determine why _pthread_mutex_init_calloc_cb () not happy?
