[Bug fortran/24866] internal compiler error

Yes, the problem is as I thought; rename the dummy and the external procedure,
say to str1, and the module compiles fine.  It also compiles if the order of
the subroutines is changed.  These are symptomatic of the symbol for str()
being made available to sub_module by host association and then having the
external attribute added to it.

This is confirmed by comparing the parse trees for the two different orders for
the subroutines.  In the case that fails, we have

          procedure name = sub_module
          symtree: str  Ambig 0 from namespace test_module
          symtree: sub_module  Ambig 0 from namespace test_module

whilst the one that succeeds has

          symtree: sub_module  Ambig 0 from namespace test_module
          symtree: str  Ambig 0
          symbol str (UNKNOWN 0)(PROCEDURE UNKNOWN-INTENT UNKNOWN-ACCESS
UNKNOWN-PROC EXTERNAL DUMMY)

I am not sure where this screw up occurs but am looking very closely at
decl.c(attr_decl1).

Paul
