Compiling the code bug.cc:
void xxx()
{
unsigned*p=0;
for(unsigned i=0;i<4;++i)
{
*p++=0;
}
for(unsigned i=0;i<4;++i)
{
*p++=0;
}
}
with the command:
/home/buchmann/devel//eo3s//tc/bin/arm-elf-gcc \
-O2 -Wall \
-c -o bug.o bug.cc
results in:
bug.cc: In function 'void xxx()':
bug.cc:1: internal compiler error: in compare_values_warnv, at tree-vrp.c:768

The failure is recent, it doesn't occur with gcc-4.3 (SUSE Linux) 4.3.2
20080806 (prerelease) [gcc-4_3-branch revision 138797].

I can reproduce it with 4.3.2 20080612 or even 4.3.1 20080428. Perhaps you
have some tree-vrp.c patches in?

Hm, I can repoduce it with plain FSF 4.3.0 and 4.3.1 as well. No
tree-vrp.c patches here, but of course other patches may as well hide
the bug here.

Thanks for the report. We now have contradictory reports about whether
this is a regression from previous 4.3 releases or not. I'll await
Richard's conclusions (and hopefully patch).

Fails with all of the 4.3 series, works for earlier releases. The problem is
still latent on the trunk.

I am sorry for wrong test for 4.3.0.
=================================================
I rebuild my gcc 4.3.0 on 2.6.9-42.7AXsmp with gmp 4.2.3 + mpfr 2.3.1.
And make a test again. It works fail.
But the following code well on gcc 4.3.2-RC1.

The following fix makes it obvious that _only_ pointer(!) induction
variables with zero(!) base are affected - thus I think this can
wait until after 4.3.2.
Bootstrapped and tested on x86_64-unknown-linux-gnu, I'll apply it
to the trunk in a moment where this issue is latent.
Richard.
