Please submit a full bug report,
As far as I debug, I find out:
/* Find the last cbranchsi4_insn in basic block BB. */
if (INSN_CODE (insn) != CODE_FOR_cbranchsi4_insn)
continue;
/* Get the register with which we are comparing. */
=> pat = PATTERN (insn);
op0 = XEXP (XEXP (SET_SRC (pat), 0), 0);
pat is NULL.
