Hi,

The problem appears in revision 201034 in version 4.9. I attached a
one-line patch that fixes it.  I also reported this problem
at http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57804

Bootstrap and regression-tested on x86_64-linux.

In method "gfc_trans_transfer()" in gcc/fortran/trans-io.c, the loop
on line 2261 should break immediately after "seen_vector" is set to
"true".

         * trans-io.c (gfc_trans_transfer): Exit loop after
         setting seen_vector.

Installed.  Thanks!

jeff
