I just tried to compile the Suse Linux package trustedgrub-1.1.3-8.27
with the GNU gcc version 4.5 snapshot 20090423.
The compiler said
boot.c:1350: internal compiler error: in execute_todo, at passes.c:1030
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
Preprocessed source code attached. Flag -O2 required.

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) ();

------- Comment #5 from rguenth at gcc dot gnu dot org 2009-04-28 21:27 -------
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).
