--- Comment #4 from Tobias Burnus <burnus at gcc dot gnu.org> 2011-07-21 10:21:22 UTC --- (In reply to comment #3) > by_value (character(kind=1)[1:_y] y, integer(kind=4) _y) Technically, it makes sense that it does not work: The caller passes <m>+<n> bytes: sizeof(str) and sizeof(strlen); in this example: 10 bytes for str and 4 bytes for the length (value: 10). How should the poor callee know which bytes belong to the string length? That's different to printf(char *format, ...): There one first knows what to expect before the unknown data comes.
