Bug#923802: pthread: dead-lock while pthread_cond_destroy()
Package: libc0.1-dev
Version: 2.25-2
Severity: normal
File: pthread
Dear Maintainer,
As checking why GSequencer's test didn't continue, I have discovered a dead-lock
as calling pthread_cond_destroy()
http://salsa.debian.org/multimedia-team/gsequencer
Here is the command to reproduce:
joel@kbsd:~/gsequencer-2.1.64$ libtool --mode=execute gdb ags_condition_manager_test
