[Bug fortran/42597] ICE with procedure pointer initialized to null()



------- Comment #1 from burnus at gcc dot gnu dot org  2010-01-04 09:55 -------
Confirmed. The initialization works - if in a procedure or program, but it
fails in the declaration part of a module.

The problem seems to be related to returning an array - one should not have
called gfc_build_null_descriptor but via get_proc_pointer_decl the routine
gfc_conv_initializer (with pointer = true and array = false).

Actually, the following looks bogus:

      DECL_INITIAL (decl) = gfc_conv_initializer (sym->value, &sym->ts,
          TREE_TYPE (decl), sym->attr.dimension, sym->attr.proc_pointer);

Namely, the last but one argument. I think, it should be:
  sym->attr.proc_pointer ? false : sym->attr.dimension
But that does not explain why it seems to work elsewhere.

Janus, what do you think?
