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.
