Compile Emacs with -DMARKER_DEBUG, and then you can call count_markers from GDB: (gdb) print count_markers(current_buffer) But you need to make sure current_buffer is the buffer you are interested in. One trick is to do this: (gdb) break Fredraw_display and then type "M-x redraw-display" with the buffer in the selected window. Then call count_markers as above, and it should return the number of markers in the current buffer.
