The issue has been fixed on the 4.9 development branch - and it is scheduled
for backporting to the 4.6, 4.7 and 4.8 release branches.

See http://gcc.gnu.org/wiki/GFortranBinaries for regular nonofficial builds and
how to build GCC yourself.

The "?" causes the problem. The "?" is rather pointless if the data is read
from a file - and for files read from stdin, it only outputs the available
items in the name list. Thus, a workaround is to either remove the "?" line, to
comment it out, or to change the "?" into "=?".

I don't know whether the workaround helps you - or updating to a fixed GCC
version. But in any case, I want to say sorry for the regression and thanks for
the bug report!
