  54 # A regression test for having a backtrace limit that forces unwinding
  55 # to stop after an inline frame.  GDB needs to compute the frame_id of
  56 # the inline frame, which requires unwinding past all the inline
  57 # frames to the real stack frame, even if that means bypassing the
  58 # user visible backtrace limit.  See PR backtrace/15558.
