In 90% of the cases, if a program crashes when compiled with
optimization but runs fine when compiled without optimization, the
problem is actually not a compiler bug.  It's just that the C language
has many "undefined" behaviors, and programmers tend to assume a lot
more than the language actually guarantees.
