Just got another crash, different line:

Program terminated with signal 11, Segmentation fault.
#0  0x00002b7bbda9d4e0 in build_uac_cancel (headers=0x0, 
body=0xa100000274,
     cancelledT=0x0, branch=<value optimized out>, len=<value 
optimized out>,
     dst=0x3609690000) at t_msgbuilder.c:1661
1661		memapp( p, cancelledT->to.s, cancelledT->to.len );
