This was also ported back to 4.5.1, causing a regression there. This is against
the policy of 'open for regression and documentation fixes'. It was also never
approved for the branch only trunk.

        * trans-array.c (gfc_trans_array_bound_check): Eliminate a redundant
        block of code.  Set name to the variable associated with the
descriptor.

Just for completeness, this testcase again emphasizes that this is an ICE on
valid code.
