Mac CRASHY_OnNSAutoreleaseNoPool: void __cdecl (void) hook

checked · by KierTaylor · submitted 2026-11-08

It reads no register or stack args. The body loads ECX = a global, EDX = LEA of the message and [ESP] = 0, calls CRASHY_HandleSystemLibraryError 0x00007401, then plain RET. It replaces the system void(void) _NSAutoreleaseNoPool breakpoint symbol: its address is stored as a hook by CRASHY_InstallHandlers (0x00006fe7) and it is never called directly, so there is no return value. This is the same shape as CRASHY_OnObjcAutoreleaseNoPool.
