[Bug fortran/45366] Problem with abstract interface to PURE function

[burnus at gcc dot gnu dot org]

------- Comment #2 from burnus at gcc dot gnu dot org  2010-08-22 11:02 -------
Note: The ABSTRACT, the INTERFACE (vs. host-association), and the
use-association of i_f do not seem to play a role.

In particular for p:
  sym->attr.pure == 0
  sym->attr.proc_pointer == 1
  sym->ts.interface->attr.pure == 1

The problems seems to be that resolve_symbol is called later than the
resolve_formal_arglist check for pureness, i.e. one first checks whether "p" is
pure before one copies the attr.pure from ts.interface->attr.pure - which
explains the failure.

I leave the fixing to Janus.
