------- Comment #3 from rguenth at gcc dot gnu dot org 2008-01-13 13:50 -------
The bug is in common_pointer_type (), where we merge the function type
qualifiers (TYPE_READONLY is used for 'const' functions):
else if (TYPE_P (exp) && TYPE_READONLY (exp) && ! TREE_THIS_VOLATILE (exp))
flags |= ECF_CONST;
volatile is used as 'noreturn'.

THis is related to PR 29382 and PR 13519. And I think this is exactly the same
issue as PR 28289.
