! { dg-do compile }

! Test the fix for PR25029, PR21256 in which references to

! assumed size arrays without an upper bound to the last

! dimension were generating no error. The first version of

! the patch failed in DHSEQR, as pointed out by Toon Moene

! in http://gcc.gnu.org/ml/fortran/2005-12/msg00466.html
