>From the dump. gfortran first generates a deferred-shape array:
    a.data = (void * restrict) &i[0];
That's fine. But instead of passing
    foo (&a);
it should pass
    foo (a.data);

In resolve.c's resolve_assoc_var, one properly sets sym->as->type =
AS_DEFERRED. 

The problem is that the code assumes that if the variable is not a pointer, it
cannot be AS_DEFERRED. From trans-array.c's 
gfc_conv_array_parameter:

7017          if (!sym->attr.pointer
7018              && sym->as
7019              && sym->as->type != AS_ASSUMED_SHAPE 
7020              && sym->as->type != AS_ASSUMED_RANK 
7021              && !sym->attr.allocatable)
7022            {
...
