[SR-Users] Kamailio 1.5.4 notls Core Dump

[Daniel-Constantin Mierla]

Hello,

probably is something triggered by a new kind of SIP message which was 
not encountered before, since there were no changes in that code. Can 
you send the output of 'bt full' in gdb?

Also, you should have the content of SIP request/reply available in core 
file, in one of gdb frames. Please send it as well.


Cheers,
Daniel
