The patch for PR 48624 at

http://gcc.gnu.org/ml/fortran/2011-04/msg00166.html

also fixes this one, so it's probably a duplicate.

For the record, 
(1) -fwhole-program is enough to see the problem,
(2) it does not occurs if used with -flto (this is why I did not see it),
(3) it does not occurs at r170284, but it does at r170493 (likely r170414),
(4) I confirm it is fixed by the patch for pr48624
(http://gcc.gnu.org/ml/fortran/2011-04/msg00166.html ).
