Hi, i downloaded the freeswitch snapshot from 16.06.07 and compiled it (with 2 little probs, i wrote it). Now i see that only the debug version is ok, with release version i get a "null pointer exception" (0xC0000005: access exception on position 0x00000060) on every call i make (portaudio->sofia and vv).

But in debug version everything is ok, what happens? regards, Thomas
