This issue does not appear with isl backend as in the configuration below.
However, I still need ppl to build gcc.
Using built-in specs.

The exception happens inside a library (ppl I suppose?). I cannot reproduce
this on x86_64-linux with GCC 4.6, nor with GCC 4.7 (both using PPL 0.11.2
but cloog 0.15.10 as from the GCC infrastructure). So I suppose the issue
might be related to the cloog version used.
You mark the bug as a regression - please fill out at least one
known-to-work version and the library versions used for bootstrapping it.

This is a cross compiler, thus I can not bootstrap it. The versions of the used
libraries are in the configure string. Or do you need the base of the build
system used to create that cross compiler?

Ok, so this eventually points at cloog issues. Still needs someone to
investigate where it traps using a debugger. Can you post a backtrace maybe?

The arithmetic exception is caught by gcc, thus not triggered in gdb. I tried a
couple of things with gdb but could not find the point at which it happens. I
will try to create a gcc variant with checking enabled. Maybe this will give
some hints about the origin of this bug.
