My patch should make the #c3 patch unnecessary, and perhaps if the problem was
somewhere deeper in the ARRAY_REF argument instead the #c3 patch wouldn't fix
ICE while what has been committed did.  Anyway, as it is fixed now, let's say
it is fixed.

Since the patch in comment #3 is doing changes in gcc/tree-scalar-evolution.c,
revision 168027 seems to be the best candidate (although I don't know enough to
rule out r168034 or even r168031):

These failures have disappeared between revisions 168021 and 168044 (see

> Try valgrind then please.

AFAICT there is no valgrind on powerpc-apple-darwin* (if I am wrong, a pointer
is welcome).

Unless I did something wrong (I just used 'make' after the patch), it does
not!-(

Unfortunately as said in comment #0 the ICE disappears when using gdb.

Created attachment 22265
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=22265
first shot at fixing this

Hi Dominique,

I cannot reproduce this bug on amd64-linux.
Could you please apply the attached patch and see if it fixes the problem?
Otherwise, could you please run gdb on f951 and report a backtrace of where it
fails?

Thanks,
Sebastian
