Another patch – the last non-Solaris '[10 Regression]'
gfortran regression, which is in Bugzilla.
The patch is obvious: assumed-rank arrays may be also
nonallocatable, nonpointer variables. They are handled
fine by this routine as it has an early exit for
dummy variables (after doing the minimal setup required).
Committed as r10-7416-g62ede14d30f5d083f1ab23bcab6e0e3c9c649006
Cheers,
Tobias
