             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:

Somehow a new NAMELIST issue was overdue ...

Also fails with and without -std=f95 (which disabled extended reads) and with
GCC 4.1 to 4.7. Thus, it is not a regression.

Using NAG 5.1, the result is:

 Opening: error.in
 JUNK
 Closed: error.in

Jerry, can you have a look?

yes, I will look.  This has become a tradition. ;)

Seems to be related to PR 49791, though the patch in PR 49791 comment 19 does
not help.

I have been working on this one. The order of the lines within the namelist
file can cause the error to go away.  I have also found that the read of the
character string acutally completes OK.  Its an elusive bug, but I am still
working to isolate it.  I o think we are leaving the chracer read in a wrong
state.  I will see if I can map it out.
