[Bug fortran/18891] New: write with no open causes core dump

["sje at cup dot hp dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I believe the attached program is legal, it works with my HP compiler, and the
basic premise of the test, write without doing an open, comes from a SPEC test.
On ia64-hp-hpux11.20, I get a core dump and putting in the open makes things
work.  I assume other platforms will show the same behaviour.  My debugger
croaks on the testcase so I don't know if I can track down the specific problem.

Test Case:

           integer ijk
C          open(unit=90)
           write(90,iostat=ierro) ijk
           end
