Actually I think this can only show up by undefined code.  Reload does:
Reloads for insn # 266
Reload 0: GENERAL_REGS, RELOAD_FOR_INPUT_ADDRESS (opnum = 1), can't combine,
secondary_reload_p
        reload_reg_rtx: (reg:CC 0 %r0)
Reload 1: reload_in (CC) = (const_int 0 [0x0])
        CR_REGS, RELOAD_FOR_INPUT (opnum = 1), can't combine
        reload_in_reg: (reg:CC 202)
        reload_reg_rtx: (reg:CC 70 %cr2 [194])
        secondary_in_reload = 0

But the only time 202 is defined is based on an uninitialized variable.
