Checking enabled it ICEs at

#2  0x00000000009ffede in execute_todo (flags=7)
    at /space/rguenther/src/svn/gcc-4_4-branch/gcc/passes.c:1017
1017        gcc_assert (flags & TODO_update_ssa_any);

after FRE:

Inserted pretmp.47_13 = VIEW_CONVERT_EXPR<v4si>(D.6253);
 in predecessor 2
Replaced p.i with pretmp.47_13 in D.6236_2 = p.i;
Replaced p.i with pretmp.47_13 in D.6236_5 = p.i;

D.6253 should be an SSA name.  I suppose a DECL_GIMPLE_REG_P setting is
missing somewhere.

Ah sorry, I've been trying to reproduce it with cc1 instead of cc1plus.

This was fixed for 4.5 by r145494, Richard's merge from the alias-improvements
branch.
