Looks like you're right and the constructors are just being emitted by machopic_asm_out_constructor() in gcc/config/darwin.c, so ASan just has no chance to add his ctor before the default one. I suppose this can be fixed in gcc/config/darwin.c, but we don't have enough knowledge and/or cycles for this. Perhaps the right thing to do is to file a bug against the owner of that file.
