*************** get_initial_def_for_induction (gimple iv
*** 2656,2667 ****
--- 2639,2664 ----
    loop_arg = PHI_ARG_DEF_FROM_EDGE (iv_phi, latch_e);

    access_fn = analyze_scalar_evolution (iv_loop, PHI_RESULT (iv_phi));
+   STRIP_NOPS (access_fn);
    gcc_assert (access_fn);

this makes gcc_assert meaningless: STRIP_NOPS will segfault for NULL access_fn
before the assert.

Thanks,
