             Bug #: 56660
           Summary: Fails to read NAMELIST with certain form array syntax
    Classification: Unclassified
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Keywords: wrong-code
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: burnus@gcc.gnu.org
                CC: jvdelisle@gcc.gnu.org, tilo@tilo-schwarz.de
        Depends on: 51825


Another namelist failure, found by Jerry. 
See also PR 49791, PR 51825, PR 55117, PR 52512.


When reading the file, gfortran fails with:
  At line 17 of file pr51825-3.f90 (unit = 99, file = 'nml.dat')
  Fortran runtime error: Cannot match namelist object name 'bb'

Using NAG, one gets the output:
 &NAML1 TRACER = XX F XX F XX F/
 &NAML1 TRACER = aa T bb T XX F/

(There are plenty ways of outputting this data - as long as the data is there.)



type ptracer
   character(len = 2)  :: sname
   logical              :: lini
end type ptracer
type(ptracer) , dimension(3) :: tracer
namelist/naml1/  tracer

tracer(:) = ptracer('XXX', .false.)
write (*, nml=naml1)

open (99, file='nml.dat', status="replace")
write(99,*) "&naml1"
write(99,*) "   tracer(:)   = 'aa' , .true."
write(99,*) "   tracer(2)   = 'bb' , .true."
write(99,*) "/"
rewind(99)
read (99, nml=naml1)
write (*, nml=naml1)
close (99, status="delete")
end
