            Bug ID: 57804
           Summary: Waste work in gfc_trans_transfer()
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pchang9 at cs dot wisc.edu

The problem appears in revision 200588 in version 4.9.

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". All the
iterations after "seen_vector" set to "true" do not perform any useful work, at
best they just set "seen_vector" again to "true".
