[issue15144] Possible integer overflow in operations with addresses and sizes.

N.B. This could probably be fixed without affecting performance by using the usual union trick.  (IIUC, that trick was technically still undefined behaviour for a while, but was eventually made legal by C99 + TC3.)  As far as I know there aren't any instances of compilers causing problems with that construct.
