[SR-Users] Kamailio Crash when modifying username of Request Uri

[Daniel-Constantin Mierla]

I looked at the last gdb trace you sent and the crash is inside syslog()
function, which prints a message with static text, if I matched it with
the right version of the sources.

Is the trace from running kamailio 4.1? What is the output of:

kamailio -v

Cheers,
Daniel
