(In reply to comment #4)
Here, I do not get any segfault/problem with valgrind (for gfortran and a.out).

I actually do not understand why "3" works. If I read gccint (cf. comment 2)
correctly I would have expect that one needs to passe the byte size. But it
seems to work as the dump / a.out indicates.
