Workaround: -Os  (optimize for code size)

I would assume that it is due to Mikael's scalarizer patch set (Rev. 180842 to
Rev. 180922), cf. http://gcc.gnu.org/ml/fortran/2011-11/msg00046.html

Similar issue exists for PRODUCT, which is not surprising as they mostly share
the same code path.

(The expr->shape is correctly set in iresolve.c - but only if the shape and dim
is known at compile time, thus not in this case.)

(I couldn't quickly find the right spot in trans*.c)
