[asterisk-dev] pthread_mutex assert core dump

[Paulo Mannheimer]

Hi folks I have been consistently having this kind of core dump in one
of my customers,

I would initially suspect of chan_spy but as the core dump occurs inside
libc, and with an assert, I was wondering if someone has experienced
something similar.
