In the first backtrace, the frame 1 was different:
``` #1 0x00007f931dc69c7e in ka_options_callback (t=0x7f91e58f05c0, type=1024, ps=0x7ffda0977bd0) at keepalive_core.c:126 ```
Did you get another core file? I need the output of `p *ka_dest` in the frame showing execution of `ka_options_callback()`. Get also the output of `list`.
