[Bug fortran/44430] [4.5/4.6 Regression] Infinite recursion with -fdump-parse-tree

------- Comment #6 from janus at gcc dot gnu dot org  2010-06-06 21:45 -------
A simple way to fix this:

Index: gcc/fortran/dump-parse-tree.c
===================================================================
--- gcc/fortran/dump-parse-tree.c       (revision 160347)
+++ gcc/fortran/dump-parse-tree.c       (working copy)
@@ -853,7 +853,7 @@ show_symbol (gfc_symbol *sym)
        }
     }

-  if (sym->formal_ns)
+  if (sym->formal_ns && (sym->formal_ns != sym->ns))
     {
       show_indent ();
       fputs ("Formal namespace", dumpfile);


I'm not 100% sure yet if this is the *proper* way, but I'll try to find out.
