------- Comment #1 from rguenth at gcc dot gnu dot org  2009-09-29 13:46 -------
Reduced testcase, fails at -O1:

typedef void (*fnt) (void);
extern inline void check3 (void)
{
  bar ();
}
void test (void) 
{
  const fnt pcheck3 = check3;
  pcheck3 ();
}

all details important: extern, the call to bar() and the indirect call in test.

static void
ipa_passes (void)
{
...
  /* Remove the bodies of extern inline functions that we never
     inlined.  */
  cgraph_remove_unreachable_nodes (false, dump_file);


that's bogus and too early.

Papered over.

./xgcc -B. -o t.o -shared attr-warn-unused-result.3.i -O -fPIC -flto

still ICEs the old way.
