[QUOTE="Richard Heathfield, post: 2509045"] Joe Wright said: Consider a string that ends in a space. while(*s == ' ') ++s; will move s onto the null terminator, which is then copied to the place pointed to by d, with *d++ = *s++ - but now s has moved *past* the null terminator, and you're in big trouble thereafter.
