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".

I can reproduce it with C only: configure --enable-clocale=gnu --with-system-zlib --with-demangler-in-ld --enable-languages=c --prefix=/usr/gcc-4.7.0 --with-local-prefix=/usr/local --enable-gnu-indirect-function --enable-cloog-backend=isl --with-ppl-include=/opt/gnu/include --with-ppl-lib=/opt/gnu/lib64 --with-cloog-include=/opt/gnu/include --with-cloog-lib=/opt/gnu/lib64 --with-fpmath=sse
FWIW: 171842 is OK, 171843 gives the comparison failure. No surprise, I suppose, but for the record...
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.
Created attachment 23856 [details] 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.
Doesn't fix the comparison failure.
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.

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? ;)

Just a note for those experiencing a comparison failure with --disable-checking, I know what's causing it and should have a fix shortly. That failure is being tracked by PR48444.
