I try to analyse this code:

int foo (int N)
{
int ftab[257];
int i, j;
for (i = 0; i < N - 7488645; i++)
j = ftab [i];

Hi Toon,
did you build with the latest cloog-ppl package. It is 0.15.7 and
available at ftp://gcc.gnu.org/pub/gcc/infrastructure/.
Gcc should build without any problems using this package. Can you verify
this?
The problem was in the cloog-ppl headers and was fixed in CLooG-ppl
0.15.4 (I think).

Hey Christiano,

Hi gcc developers, hi graphities
here are some notes from our weekly phone call. Unfortunately I missed
to send out the notes from the last two phone calls, but I hope to get
them out more regulary. Believe in me! ;-)
