| ! 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 |
