Downloading Fedora 14 now, but that'll take a while to get set up.

Potentially helpful would be scheduling dumps from stage1 and stage2 compilers
for these files; use "-da -fsched-verbose=5".

Can you try

It is a very fast machine.

--- Comment #18 from Steven Bosscher <steven at gcc dot gnu.org> 2011-04-02 19:16:17 UTC ---
Something appears to be wrong with the allocation of scheduled_insns:

* It is VEC_alloc'ed on the heap in sched_extend_ready_list() but it is never
VEC_free'ed.

* It is allocated if sched_ready_n_insns == -1, which is the initial state
("static int sched_ready_n_insns = -1;") and also the state after
sched_finish_ready_list(). Therefore, AFAICU, a schedule_insns VEC is leaked
for each region.

I would have VEC_alloc'ed schedule_insns once, at the start of the scheduler,
and VEC_reserve elements in sched_extend_ready_list().  But I am not
sufficiently familiar with the scheduler to propose a patch.

Attempt at correcting memory management for scheduled_insns

Currently trying to see if this bootstraps. Even if this is not the fix for the
comparison failure, something like this still ought to be applied to correct
the usage of the VEC data structure.

Okay, the problem showed up on Fedora 14 (no idea why only there). The bug is
that I've missed some uses of last_scheduled_insn. Will probably be able to
post a fix on Monday.

Perhaps the patches can be reverted until it's clear what is wrong here? The
trunk is now broken for 3 days, it will make things like bisecting regressions
much harder later on if it stays broken even longer.

Confirmed.  Reduced testcase for -O2:

typedef __builtin_va_list va_list;

extern void exit (unsigned);
extern int vfprintf (void *s, const char *format, va_list arg);
extern void *stderr;

void fatal (const char *format, ...)
{
  va_list ap;
  __builtin_va_start(ap,format);
  vfprintf (stderr, format, ap);
  __builtin_va_end(ap);
  exit (1);
}

But x86/Linux, x86-64/Linux, x86-64/Darwin, x86/Solaris and SPARC/Solaris now
bootstrap fine for me so there is some progress.

I can confirm that r171959 with --enable-checking bootstraps on
f14/x86_64/linux, which was not previously the case. Thanks Bernd! I can also
assert that it still fails with --disable-checking.

Do I open a new bug report for the --disable-checking bootstrap failure or are
we working backwards through the bugs to get back to a known good state with
this one?
