[asterisk-dev] FreeBSD Asterisk Segmentation Faults

[J. Oquendo]

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

It even crashed GDB and gave inconsistent information... First it
gave:

[sil at bordello ~]$ sudo gdb asterisk asterisk.core
....
Core was generated by `asterisk'.
Program terminated with signal 11, Segmentation fault.
#0  0x282a74ab in ?? ()
(gdb) bt
.....
#1424 0x08135480 in ?? ()
#1425 0x080b2454 in ast_utils_init () at utils.c:504

....

Second time after retrying asterisk to get a new asterisk.core, I
did another bt... It scrolled past #8800 with the majority if lines
coming in at 0x00000000 and kept going on and on and on...

While in gdb
