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