Most likely the same bug as PR 9971 but with a different code.

I can confirm this on the mainline (20030827).
Reduced source:
void DecodeAC(int index,int *matrix)

Something here is causing it:
>From loop.c:
4030 /* Prefetch might be worthwhile only when the loads/stores are dense. */
4031 if (PREFETCH_ONLY_DENSE_MEM)
4032 if (density * 256 > PREFETCH_DENSE_MEM * 100
4033 && (info[i].total_bytes / PREFETCH_BLOCK <--- I want to say
this guy is causing it
4034 >= PREFETCH_BLOCKS_BEFORE_LOOP_MIN))
And it is PREFETCH_BLOCK is defined as ix86_cost->prefetch_block which is zero at
this point because we are tuning for i486 (which does not have prefetch at all) but our
arch is pentium4 which does have prefetch so we try to use prefetch but we need to
figure out if it is good to prefetch so we do a divide on PREFETCH_BLOCK but since
PREFETCH_BLOCK is zero here, we get an floating exception.

I think this patch will fix it but I have no way to test it as bootstrap fails for me before
applying the patch (once GCC gets back bootstrapping, I will submit this):

A different question is shouldn't -march=pentium4 -mtune=i486 be declared invalid?
To me, tuning (ie scheduling) for a processor that is less than the baseline
architecture (which -march specifies) just seems wrong.
The 486 didn't know about SSE2, it didn't know about SSE, it didn't know about
MMX, it didn't even know about CMOV, but by specifying -march=pentium4 all of
those features are enabled. So, there is no way for the scheduler to come up
with a correct schedule.
