Even that will behave differently, just because the alpha may have different

lint is, IMHO, too silly.

That's not a problem, there's no change there. IMHO, casting to and from
(void *) is bad mojo in most contexts.

My advice would be to first go with the assumption that there's somplace
where you allocate too little space.
In particular, look for malloc(0). If you have a typo that results in no
space being allocated, you still get a valid pointer to at least 0 bytes
