--- Comment #2 from Tobias Burnus <burnus at gcc dot gnu.org> 2011-08-24 06:19:59 UTC --- Seems to be a duplicate of the regression caused by the patch for PR 50050, see bug 50050 comment 7. Draft patch posted at http://gcc.gnu.org/ml/fortran/2011-08/msg00199.html Sorry for the breakage! Work around: Use a version before Aug 22, 2011 - or apply Mikael's patch - or wait a couple of hours until it has been committed and then recompile.
