Segmentation fault in Asterisk chan_iax2

[Yahya]

Binary package hint: asterisk

Asterisk crashes randomly with SIGSEGV somewhere in chan_iax2.so module. The crashes are quite infrequent. I've had 3 or 4 crashes over the last two weeks, however this is a lightly used server with only 3 users. I've attached gdb backtraces with debug symbols.
