--- Comment #4 from anlauf at gcc dot gnu.org ---
The bug triggers with -ffrontend-optimize, thus confirmed.
The problem shows up with the implied loop over j in the read statement,
which runs over the second dimension. Transposing the array and adjusting
the code appropriately it does no longer fail.
Workaround: compile with -fno-frontend-optimize until a fix is available.
