If so, what markers could be involved? what were you doing when this happens? This part of the C backtrace seems to indicate that some overlay is involved that specifies its own keymap: #24 0x000000000051dcc4 in marker_position (marker=) at /home/sds/src/emacs/trunk/src/marker.c:777 #25 0x0000000000514667 in overlays_at (pos=77003, extend=0, vec_ptr=0x7fffffffccd8, len_ptr=0x7fffffffcce0, next_ptr=0x0, prev_ptr=0x0, change_req=0) at /home/sds/src/emacs/trunk/src/buffer.c:2541 #26 0x00000000005bc60f in get_char_property_and_overlay (position=308012, prop=12156402, object=43556693, overlay=0x0) at /home/sds/src/emacs/trunk/src/textprop.c:626 #27 0x00000000005b9756 in get_local_map (position=, buffer=0x2989f50, type=12156402) at /home/sds/src/emacs/trunk/src/intervals.c:2306 #28 0x00000000004febe7 in read_key_sequence (keybuf=0x7fffffffcf40, prompt=11966850, dont_downcase_last=0, can_return_switch_frame=1, fix_current_buffer=1, bufsize=30) at /home/sds/src/emacs/trunk/src/keyboard.c:9147 Do you have any guesses as to what that overlay might be?
