Hi all,

I'm getting alternate failing tests (my own tests) on macOS with this from lldb:

Process 13623 stopped

then I get:

    frame #20: 0x00007fff207aff3d libdyld.dylib`start + 1

then all good:

[ OK ] test_route_regex_check
[ RUN ] test_sip_message
[ OK ] test_sip_message
[==========] 14 test(s) run.
[ PASSED ] 14 test(s).
Process 15176 exited with status = 0 (0x00000000)

Am I cleaning up correctly?
