[Bug c++/79373] For loop optimization bug: condition ignored

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79373 --- Comment #6 from Andrew Pinski --- Once undefined behavior happens all bets are off of any behavior of the program. In this case the function is in lined and the optimizers see i cannot overflow the multiply so it removes the loop check.

[Bug c++/79373] For loop optimization bug: condition ignored

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79373 --- Comment #5 from Steven Pigeon --- The problem is not the function that overflows. It's the loop that calls them that never stops. I don't see how that's "resolved": the overflow in the function should not affect the loop that calls it.
