            Bug ID: 60322
           Summary: Incorrect bounds on polymorphic dummy array
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org

Simple complete program should print that the lower bound is 0, but reports
"1".

The attached reproducer shows that the bounds are incorrect for a polymorphic
dummy argument when an array constructor is passed as the actual argument.  If
an actual array variable is passed, the behavior is correct.

This seems simple enough that I was sure there would be a bug report, but the
few that I found that were at least in this direction were not obviously the
same, and this reproducer is much simpler in any event.

Fails on Mac OS X 10.8.5 with 
GNU Fortran (MacPorts gcc47 4.7.3_3) 4.7.3
GNU Fortran (MacPorts gcc48 4.8.2_0+universal) 4.8.2
GNU Fortran (GCC) 4.9.0 20140103 (experimental)
