Confirmed.

#1  0x084a7d71 in execute_todo (flags=7)
at /home/richard/src/trunk/gcc/passes.c:1031
1031gcc_assert (flags  TODO_update_ssa_any);
(gdb) 
#2  0x084a8772 in execute_one_pass (pass=0x8d26100)

(gdb) p *pass
$1 = {type = GIMPLE_PASS, name = 0x8bdb857 fre, gate = 0x86d780f gate_fre, 
  execute = 0x86d77fb execute_fre, sub = 0x0, next = 0x8d25680,

  properties_provided = 0, properties_destroyed = 0, 
  todo_flags_start = 524288, todo_flags_finish = 7}

Reducing.

Reduced testcase.  Fails at -O1.

typedef void (*entry_func) (void) __attribute__ ((noreturn));
extern entry_func entry_addr;
static void bsd_boot_entry (void)
{
  stop ();
}   
void bsd_boot (void)
{
  entry_addr = (entry_func) bsd_boot_entry;
  (*entry_addr) ();
}

We need to update SSA form after FRE as we now notice the cast to
entry_func (with noreturn attribute, thus no VDEF) was invalid (and
thus we add a VDEF).
