Description:
------------
I was just reading through recent commits and saw this for zend/zend_virtual_cwd.h (commit# 647ebe6bf214d1a30627bab1758b66262d2f780f)

-       (len >= 2 && ((/* is local */isalpha(path[0]) && path[1] == ':') || /* is UNC */IS_SLASH(path[0]) && IS_SLASH(path[1])))
+       (len >= 2 && (/* is local */isalpha(path[0]) && path[1] == ':' || /* is UNC */IS_SLASH(path[0]) && IS_SLASH(path[1])))

I could be forgetting my order of operations, but I think the lack of grouping and similar operations causes LTR here... Shouldn't the proper parenthetical grouping be:

       (len >= 2 && ((/* is local */isalpha(path[0]) && path[1] == ':') || (/* is UNC */IS_SLASH(path[0]) && IS_SLASH(path[1]))))

Here it is tabulated for clarity:

(
	len >= 2 &&
	(
		(
			/* is local */
			isalpha(path[0]) &&
			path[1] == ':'
		) ||
		(
			/* is UNC */
			IS_SLASH(path[0]) &&
			IS_SLASH(path[1])
		)
	)
)
