Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

Author CC:ed, preprocessed code and gdb backtrace to be added.

Since the other report was for ia64, it might matter that the only similarity
with crisv32 (aka. cris-*-* -march=v32) is that neither target takes offseted
expressions as addresses (mem (plus reg ...)), just indirect (mem reg).
