[Bug middle-end/38520] [graphite] wrong code with -O3 -fgraphite-identity on polyhedron benchmarks

[dominiq at lps dot ens dot fr]

------- Comment #3 from dominiq at lps dot ens dot fr  2008-12-14 17:32 -------
Compiling mdbx.f90 with "-m64 -O3 -fgraphite-identity -floop-block
-ftree-loop-linear -fno-strict-overflow" gives an ICE:

mdbx.f90: In function 'mstep':
mdbx.f90:822: internal compiler error: Bus error
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

The test compiles and gives a correct excutable if -m64 is removed.
