Program received signal SIGSEGV, Segmentation fault.

(insn 9 8 10 2 (set (reg:V2DI 91 [ vect__3.9 ])

(nil))
the vec_select has a NULL operand somehow. We're expanding from
vect__3.9_16 = (vector(2) long unsigned int) vect__2.8_15;
so likely Uros change or it triggers a bogus expand helper or forwprop
does not properly constrain itself. I'll debug a bit.
