Created an attachment (id=19903)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=19903&action=view)
different testcase, reduced

Fails at all -O1, -O2 and -O3 levels. I am not sure if it is the same problem,
but it fails at the same place, so I am attaching it here.

$ /mnt/svn/gcc-trunk/binary-156830-lto/bin/g++ -O1 -fgraphite-identity -c
pr43026-2.C
pr43026-2.C: In function ‘(static initializers for pr43026-2.C)’:
pr43026-2.C:10:4: internal compiler error: in expand_scalar_variables_expr, at
sese.c:902
