Does this happen when you quit, or randomly at some point during runtime?

[julienaubert]

Each time when I quit.

OK, in this case, can you try to run Protonect from gdb and post a stacktrace from the segfault?

[julienaubert]

Actually, it only occurs if I ctrl-c to exit. Running with gdb (using signal cmd in gdb to pass it to program):

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_INVALID_ADDRESS at address: 0x0000000000000000

Fixed by #275.
