this is a probably a case that was already fixed in the invalid_ctypes lint (I don't remember the issue number off the top of my head)

not having tested it myself, this is probably #113900 which was fixed by #113921
It was reported for this crate. The PR seems safe to backport if deemed important enough.

#113921 was backported in #114748.
