[OpenSIPS-Devel] how to handle memory corruption issue

[Bogdan-Andrei Iancu]

Hi Loring,

It seems you came across a memory corruption or so.

Regarding the compiling of mem debugger and the failure to start the 
postgres module, I suspect you have not re-compiled the postgres module 
after changing the options in Makefile.

Regards,
Bogdan
