It has been a long time since I make sure my codebases have `-Wall -Werror`. This bug is from 2003 both when that wasn't as common & when compiler diagnostics weren't as good/reliable.

This code would not trigger under -Wall -Werror. Try it.

In the general case that OP was talking about, not for underhanded code, my comment holds.
