[Bug fortran/32881] PURE attribute escapes from contained procedure



------- Comment #1 from burnus at gcc dot gnu dot org  2007-07-24 17:22 -------
Confirmed.

The problem is that  gfc_pure(NULL) is called and thus
  sym = gfc_current_ns->proc_name;
is used as procedure symbol, which is "bar" and not "foo".

The following patch fixes this, but I have not regtested it.

-  is_pure = gfc_pure (NULL);
+  is_pure = gfc_pure (lvalue->symtree->n.sym->ns->proc_name);

   if (is_pure && gfc_impure_variable (lvalue->symtree->n.sym))
