I concur.

OK - though, I have some questions and nits:

a) Shouldn't the following be the following a once ("1") instead of a 
twice ("2")?

+! { dg-final { scan-tree-dump-times "func" 2 "original" { xfail *-*-* } } }


b) I miss a run-time test.

c) I get an ICE for:
   integer :: a
   associate (b => a)
   end associate
   end
Error: Association to variables is not yet supported at (1)
f951: internal compiler error: in gfc_enforce_clean_symbol_state, at 
fortran/symbol.c:3451

How about using gfc_fatal_error instead of gfc_error - or something else 
which avoids the ICE?
