Thus, the structure definition musl has right now will give the right layout to match the ABI, and in fact it works perfectly when compiled with GCC. I'm not entirely opposed to putting the explicit padding in there, since this is an arch-specific structure anyway, but I think you should check your compiler. The same issue might come up elsewhere and might not be so easy to work around. Let me know what you find. Rich
