Is memset and memcmp compatible with strict aliasing? Intuitively it seems like that would be a gap into the aliasing rules. Altough void* is allowed to alias anything so maybe it works through that. Ive never seen memset, memcpy or memcmp on anything but char* in production code.
The aliasing rules only talk about dereferencing pointers. Void* can't be dereferenced so it has no interaction with the aliasing rules. You might be thinking about char, and yes, you are allowed to dereference char to inspect the bytes of an object, which is what the various mem* functions do under the hood.
