 [ compiles as though he had written
	i = (*cp << 8) + *cp, cp += 2; ]

No bug here, consult your C manual.  C only promises that a postfix ++ will
be executed before the next sequence point and the only sequence point here
is the end of the statement.  Try this instead:

	i = (cp[0] << 8) + cp[1], cp += 2;
