size_t is unsigned, so the -10 is cast to unsigned too for the 
comparison which yields some huge number.

Comparing signed to unsigned is almost always a mistake... but 
one D inherited from C.

This is a reason why I prefer to use int instead of size_t where 
I can but that might require casts and truncation too.
