[Bug fortran/21224] New: Error when reading arrays of strings in namelist input in gfortran

["mfatenejad at wisc dot edu" <gcc-bugzilla at gcc dot gnu dot org>]

// Here is the exact command I used to compile my program for this bug report:

gfortran_temp/irun/bin/gfortran -save-temps test.F90

// Here is the exact output I get at the command line:

test.F90: In function 'MAIN__':
test.F90:9: internal compiler error: in gfc_conv_string_parameter, at
fortran/trans-expr.c:1986
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

// Here is the file test.f95 that was generated with the -save-temps option

# 1 "test.F90"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "test.F90"
program test

  implicit none

  character(len=20) :: var(20)

  namelist / input / var

  open(unit=10, file="test_file", form='formatted', status='unknown')
  read(10, nml=input)

end program test

Sorry I wrote out test.f95 here here...I didnt see anywhere on bugzilla to
attach files, and this is my first time posting a bug.

The problem seems to occur when I use namelist input to read an array of strings
. If I read 1 string only, there is no error. I encouterred this problem when
working on a larger program, which I was able to compile on three separate
fortran 90 compilers on many platforms.

Thank You
