[sr-dev] 3.1 crashes in topoh on receiving 180 message

I'm trying to get Kamailio 3.1 running with topoh module. It crashes in topoh trying to decode tha param. I can post the config file, but there's nothing special to it. The only non-default topoh parameter is: modparam("topoh", "mask_ip", "93.153.XX.YY") SIP trace and backtrace below: ### U 92.249.89.223:6230 -> 93.153.XX.YY:5060 INVITE sip:000100@93.153.XX.YY SIP/2.0.
