[OpenSIPS-Users] opensips crash

[Bogdan-Andrei Iancu]

Hi Daniel,

could you check if in sources, in modules/tm/t_fwd.c +132 the line is:
    memcpy( p, request->dst_uri.s, request->dst_uri.len);

what SVN reversion are you running ?

Thanks for the scenario, but I come back to my question - is the crash 
reproducible ?

Regards,
Bogdan
