             Project: Asterisk

      Security Level: None
    Affects Versions: 1.8.28.2, SVN

Jeez. Finally found out why I didn't get core dumps most of the time.

res_musiconhold does a chdir to a non-writable directory (since r4552). That chdir is completely avoidable, as far as I can tell.

If run quickly enough, that chdir is undone at the end of the function, but because of the race, a second run of the function will take the temporary cwd as old cwd and return to that when finished:
*from now on, you're in a non-writable musiconhold dir, and you get no core dumps (unless you run as root or your moh dirs are writable or your core_pattern is absolutely pathed).*
