That was a side effect of my Patch for 36476:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36476
"ICE: len=* CHARACTER array with separate PARAMETER statement"

Actually, I'm not sure whether it worked before: At least with 4.3 I
always got a segmentation fault (after all three lines were correctly
printed); though with some version of gfortran shortly before fixing
36476 it didn't gave a segmentation fault.
