[Bug tree-optimization/33834] New: [4.3 Regression] ICE in vect_get_vec_def_for_operand, at tree-vect-transform.c:1829

[tbm at cyrius dot com]

I get the following ICE with current trunk and -O2 -ftree-vectorize.
I see this ICE with gcc from trunk going back to 2007-04-22, but
not with 2007-03-26.
