Then you'd better not put a string into "tmp" that has more than *ONE*
character in it, as a 2-element array of "char" has room for a
1-character string - 1 character, plus the terminating '\0'.

2-character strings as in "XY", or 2-byte strings as in "X" (1 byte of
'X', one byte of '\0')?

if it's the former, you'd better do

	char tmp[3];

instead (there's no need to initialize it to 0).  If you try to copy a
2-character string to a 2-element array of "char", all sorts of random
things can happen.
