            Bug ID: 70235
           Summary: Incorrect output with PF format
           Product: gcc
           Version: 4.8.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: agardeux.ge at gmail dot com
  Target Milestone: ---

Consider the following formatted output using PF format:
      program fmt
      implicit none
      real*8 y
      y = 1.0e4
      print '(a, -6PF8.3)', '-6PF8.3 y = ', y
      end program fmt

gfortran 4.8.2 and 4.9.3 give an incorrect result:
-6PF8.3 y = ********

Tested with:
   GNU Fortran (Ubuntu 4.8.2-19ubuntu1) 4.8.2
   GNU Fortran (GCC) 4.9.3 <mingw32>

The output is correct with gfortran 4.4.7:
-6PF8.3 y =    0.010

Tested with:
   GNU Fortran (GCC) 4.4.7 20120313 (Red Hat 4.4.7-11)
