The previous code reported 2 frames per section. The new code uses the save_stack_trace facility to save an arbitrary number of frames (currently set to 5 via a #define) For what its worth, these patches assisted me with debugging some issues in -rt. The second patch is really a workaround for where X86_64 frame-pointers apparently are not working under certain circumstances.
