I'm not familiar with it. See the other queries being handled in server.c:handle_query. Literally, see the require_running (own_buf); calls. If you connect with "target extended-remote" instead of "target remote", and do "compare-sections" before issueing "run" or "attach" from gdb, hence gdbserver has no inferior process to debug yet, you want gdbserver to reply error (E01) instead of trying to read from a non-existing inferior process (and possibly crashing). -- Pedro Alves
