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