It has been pointed to me via mail that my analysis of the memcpy 'bug'
missed the real point: That converting a pointer with loose alignment
requirements to a pointer with stricter alignment requirements is permitted
to cause undefined behaviour (even if the "stricter" pointer is not
dereferenced, or is dereferenced only after conversion back into a
"looser" pointer). I will withdraw my complaint. Thanks to everyone who
bothered to educate me on the subject.
