[OpenSIPS-Users] Strange segfault when calling check_fraud

[Jim DeVito]

Hi All,

Wondering if you have seen something like this. It happens when calling 
check_fraud() like this...

check_fraud("$fU", "$rU", "1");

I can reproduce it on 2 of my 3 servers. Let me know if there is other 
debugging info that may be needed.

Thanks!!
