Absolutely there is a reason. Exceptions are very expensive, especially in low-level functions. In the situation you're talking about, it's a simple logic error in the calling code. That situation will never happen in bug-free code. This is very different from the situation with something like a file operation where "disk full" is a genuine exceptional situation.
