[reSIProcate] Exception can not be catched by a try/catch block

[Scott Godin]

Do you know what exception is being thrown?  Could it be the assert in
compute2543TransactionHash that is triggering the core dump, and not an
exception?  Can you post the SIP message or Via header that is causing the
problem for you, or a short test program that demonstrates the issue?
 Note:  take a look at resip/stack/test/testSipMessage.cxx for a sample of
how to create a quick SipMessage test program.

Regards,
Scott
