simple test case
Optimization bug at -O2, -O3 with message
vr = matmul( orth(:,:,n), v )

Error: The upper bound in the last dimension must appear in the reference to
the assumed size array ‘orth’ at (1) lhcal.f90:33:25:
Attached test case is taken from larger program, and only appears to be a
problem if orth is an assumed size arrays with the * in the last dimension. (If
assumed shape, also fine.) Obviously easy to work around, so minor.
