Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.6/README.Bugs> for instructions.
Preprocessed source stored into /tmp/ccbwMOGo.out file, please attach this to your bugreport.


Notes:
1) No ICE with -O1.
2) Changing n_elts to 2 avoids the ICE.
3) Compiles correctly with GCC 4.4.6.
