Created attachment 6114

catch multiplication as well as addition overflows
Jeff Law's work-in-progress patch misses some problematic overflows. This is
because the integer multiplications may overflow too. Attached is an
untested patch that catches the problematic overflows that I found
by inspection. This patch does not attempt to catch all overflows, only
those that might corrupt memory.
