Depends on your definition of "correct software". I'd say correct 
software has no bugs at all...

Anyway, I can think of cases where the usually correct assumption is 
made that the floating  point delimiter is one byte, while some locales 
maybe need two bytes. This could then of course lead to memory 
corruption when using sprintf with a too small buffer.
