I honestly don't see what's causing the crash...
Code:
memcpy(npc_type, npc_type_to_copy, sizeof(NPCType));
should not be reached if 'npc_type_to_copy' is nullptr - which I verified a valid or nullptr reference should be returned.
And since
Code:
NPCType* npc_type = new NPCType;
memset(npc_type, 0, sizeof(NPCType));
don't appear to be causing issues, I don't see 'src' as being nullptr.
Since we're actually getting into the memcpy() routine, it doesn't look like server code at this point.
Unfortunately, that's an asm sub-routine and tracing code flow doesn't appear possible :(
I did find a few obscure references to memcpy and VS2013..but, nothing to validate the problems posted in the dump log...
(Still digging...)
EDIT: If you're building on 'debug', try switching to 'release' - also, make sure that you clean your solution before building again.
