Description of problem:
On my small test problem (I will attach it) I get:
$gfortran bug.f90
bug.f90: In function 'MAIN__':
bug.f90:19: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://bugzilla.redhat.com/bugzilla> for instructions.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.get the file bug.f90 (attached)
2.run  "gfortran bug.f90"

Actual Results:  See the Description

Expected Results:  I should have gotten some sort of compilation error, for example:
$ifort bug.f90
fortcom: Error: bug.f90, line 24: A CHARACTER data type is required in this context.   [ACCESS]
       ACCESS=acc, &
compilation aborted for bug.f90 (code 1)

Additional info:

Just in case the attachment doesn't work, here's the code:

  CHARACTER(LEN=80) :: fln
  CHARACTER(LEN=40) :: stat, frm, posi
  CHARACTER     :: type
  INTEGER       :: iunit, fmode, format, errcod
  LOGICAL       :: filexs

  fln = '/home/steve/models/225a/gamsmatr.scr' 
  iunit = 17
  WRITE (6,*) 'opening file ', TRIM(fln)
  IF (.NOT. filexs) THEN
     WRITE (6, *) 'Failed EXIST inquiry on file '//FLN
  stat = 'OLD'
  posi = 'REWIND'
  type = 'R'
  OPEN(UNIT=iunit, &
       FILE=fln, &
       STATUS=stat, &
       FORM=frm, &
       ACCESS=acc, &
       POSITION=posi, &
       IOSTAT=errcod, &


  991 WRITE (6, *) 'File open error: ', errcod
