Or, rephrasing the above ">", sometimes you get:

	The optimization was a success, but the program died.

I can't see this is anything other than a conflict resulting from either a
bad (or simply incomplete) language definition or a broken compiler.  But
then I've always had trouble dealing with compromises between efficiency
and correctness.
