Summary:                    SIGSEGV ast_read from
ast_channel_bridge/..generic_bridge, chan->tech==0x2
Description: 
Random segfaults on 1.4.17 every couple of days or so - nothing abnormal
logged (debug 10/verbose 10). This is a moderately busy SIP-only PBX, with
realtime (ODBC) queues and AMI in use. I'll attach a full backtrace
(DONT_OPTIMIZE), slightly sanitized.
