2010/8/30 gwillingham@comcast.net:
We were experiencing the issue with 1.5.4 released version, we upgraded from svn and the issue still persists. I have a backtrace from both versions.
I agree it is a free of a null pointer, but the if(hf->parsed) should be the test for NULL, and only execute code if not NULL. However this test is failing.
Do you have a SIP flow/trace to reproduce the crash?
