Created attachment 25118
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25118
reduced testcase (the same as gfortran.dg/graphite/id-pr47691.f)

Even after fixing PR47691, the same ICE is sometimes reached with
-fno-tree-scev-cprop.

Compiler output with the attached testcase:
$ gcc -O -fgraphite-identity -ffast-math -fno-tree-scev-cprop -fstrict-overflow
testcase.f 
testcase.f: In function ‘MAIN__’:
testcase.f:2:0: internal compiler error: in create_linear_expr_from_tree, at
graphite-sese-to-poly.c:1137
Please submit a full bug report,
