I'm using gcc 4.7.2 and when trying to compile Firefox 17 with the following
options:

-march=native -O3 -mno-avx -pipe -floop-interchange -floop-strip-mine
-floop-block

It results in the following:

My Parma Polyhedra Library version is:

ppl-config --version
0.11.2

Should I updated to 1.0 version?

Same error for me. For 4.6.3 -O1 -fgraphite-identity (or any other graphite
flag) is enough to trigger an ICE, for 4.7.2 -O2 and a graphite flag is
required to trigger it. I'm attaching the preprocessed source and a reduced
testcase.

Reduced testcase for graphite related ICE

Reduced testcase. Crashes with gcc -O2 -fgraphite-identity -c fft.i

The bug is reproducible w/ the following reduced testcase:

void
de(void)
{
  static int ey;
  static int ux;
  short int mb;
  int al;
  int vx;
  int *gs = &al;
  int *dp = &ux;
  for (ey = 0; ey < 2; ++ey)
    *dp = (mb += *gs) || vx;
}

% gcc-4.7.3 -c -O2 -ftree-loop-linear 6b94b1d3.c
6b94b1d3.c: In function 'de':
6b94b1d3.c:2:1: internal compiler error: in scan_tree_for_params_right_scev, at
graphite-sese-to-poly.c:633

gcc 4.8 and 4.9 are not affected. However, they segfault on quite a similar
code from 59817#c2.

Should be fixed now.
