Bug#507883: asterisk: Very frequent segfaults on startup

[Lars Bensmann]

Package: asterisk
Version: 1:1.4.21.2~dfsg-2
Severity: normal

Asterisk crashes very frequently on startup. Using safe_asterisk will
start it eventually. Once it's running it's stable. The last start took 90
attempts. The one before that 71.

The backtraces all look the same (OK, I just checked four of the 159 core
dumps :-)

Before using the Debian package I was using a self-compiled build (1.4.18,
I think) and had no such problems.
