[OpenSIPS-Users] get_source_group not working

[Bogdan-Andrei Iancu]

Hi Wesley,

The first frames of the core are bogus ... :(...the crash happens in the 
"check_ip_address" function because the name param is empty, but I 
cannot see where it is called from , to identify the bug.

Are you sure the crash is triggered by "check_source_address" function ?

Regards,
Bogdan
