Hello back,
Thanks Ovidiu - I reproduced the problem with the other function
"uac_replace_from" too, in a x86 server, OpenSips 1.10 tls..
here you can find the bt full of gdb :

This GDB was configured as "x86_64-linux-gnu".

Take a look here how to enable core dumps:
http://www.opensips.org/Documentation/TroubleShooting-Crash
Even if it's an ARM, you should be able to get a core dump.
