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=57801

Bootstrap and regression-tested on x86_64-linux.

In method "resolve_variable()" in gcc/fortran/resolve.c, the loop on
line 4908 should break immediately after "seen" is set to "true".

         * resolve.c (resolve_variable): Exit loop after setting seen.

Installed.  Thanks.

jeff
