             Bug #: 51825
           Summary: Fortran runtime error: Cannot match namelist object
                    name
    Classification: Unclassified
           Product: gcc
           Version: 4.5.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: chrisonian@gmail.com


Created attachment 26301
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26301
simple program that produces namelist error

The attached program fails with:

 Opening: error.in
At line 42 of file error.f90 (unit = 2, file = 'error.in')
Fortran runtime error: Cannot match namelist object name 3

The file 'error.in' is created by the program, with contents:

&error_params
  beam_init%chars(1)='JUNK'
  beam_init%grid(1)%n_x=3
  beam_init%grid(1)%n_px=2
/

I've tries this with gfortran 4.5.3 on OSX (via MacPorts) and gfortran 4.5.1 on
Linux, with the same error. I believe this is different from other namelist
bugs posted. Here is my OSX information:
