Thanks a lot Peter for your help!
Also if you have not already, build with cmake -DENABLE_ASAN=1. I suspect that it might blow up with a use-after-free warning before the NULL pointer dereference.
Yes, you're right. After compiling it with -DENABLE_ASAN=1 and -DCMAKE_BUILD_TYPE=Debug it fails at: * thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0x0) frame #0: 0x00007fff588c9d89 libsystem_platform.dylib`_platform_memmove$VARIANT$Haswell + 169 libsystem_platform.dylib`_platform_memmove$VARIANT$Haswell: -> 0x7fff588c9d89 <+169>: movq (%rsi), %rcx 0x7fff588c9d8c <+172>: movq (%rsi,%rdx), %r8 0x7fff588c9d90 <+176>: movq %rcx, (%rdi) 0x7fff588c9d93 <+179>: movq %r8, (%rdi,%rdx) Target 0: (Wireshark) stopped. ---- ================================================================= ==18967==ERROR: AddressSanitizer: SEGV on unknown address 0x000000000000 (pc 0x7fff588c9d89 bp 0x7ffee4d3a9c0 sp 0x7ffee4d3a9c0 T0) ==18967==The signal is caused by a READ memory access. ==18967==Hint: address points to the zero page. #0 0x7fff588c9d88 in _platform_memmove$VARIANT$Haswell (libsystem_platform.dylib:x86_64+0x1d88) #1 0x10e624854 in __asan_memcpy (libclang_rt.asan_osx_dynamic.dylib:x86_64h+0x59854) #2 0x116c36936 in isakmp_init_protocol packet-isakmp.c:5866 #3 0x118e76e4a in call_routine packet.c:247 #4 0x10d8637ec in g_slist_foreach (libglib-2.0.0.dylib:x86_64+0x5c7ec) #5 0x118e76f59 in init_dissection packet.c:328 .... So I will have a look at the UAT part.
