The C++ ABI requires dylibs to pass a pointer to __cxa_atexit which does e.g. cleanup of static global variables. The C++ spec says that the pointer can point to any address in one of the dylib's segments, but in practice ld64 seems to set it to point to the header, so that's what's implemented here.
