Hello Gene,

1.5.4 was released in February, i think - do you use the version from tar.gz? 
I've checked the file in question, there were one fix in the last month:

r6036 | miconda | 2010-07-30 20:18:33 +0200 (Fr, 30 Jul 2010) | 4 lines
- fix off-by-one bug for quoted parameter values in parse_to
- patch by Alex Hermann, SF#3035382

which maybe could help you here. I'd suggest that you extract the SIP message 
in question from the backtrace (receive_msg, buf) and then try to reproduce 
the crash. If it crash again, just update to the latest 1.5 branch state, and 
see if it crashes again. It contains some more fixes, one or two also could 
cause crashes in some special conditions.

Cheers,

Henning
