When I compile the module listed below using the version of gfortran for Linux
dated August 27 (downloaded from http://gcc.gnu.org/wiki/GFortranBinaries), I
get the following error:

p.f90: In function 'i':
p.f90:5: internal compiler error: in make_decl_rtl, at varasm.c:1263
Please submit a full bug report,
with preprocessed source if appropriate.

MODULE print_it
CONTAINS
  SUBROUTINE i()
    LOGICAL :: qexist
    INQUIRE (UNIT=1, EXIST=qexist)
  END SUBROUTINE i
END MODULE print_it

This appeared at some point between 20070821 [rev 127667] and 20070827 [rev
127830]. Most likely culprit at this point is:

2007-08-26  Jerry DeLisle  <jvdelisle@gcc.gnu.org>

        PR fortran/33055
        * trans-io.c (create_dummy_iostat): New function to create a unique
        dummy variable expression to use with IOSTAT.
        (gfc_trans_inquire): Use the new function to pass unit number error
info
        to run-time library if a regular IOSTAT variable was not given.

------- Comment #2 from jvdelisle at gcc dot gnu dot org  2007-08-29 01:27 -------
I think the problem has to do with not having a backend_decl associated with
the dummy variable expression created.  I will not be able to get to this
quickly, so I will revert the patch until I get this fixed.

Thanks for the report.
