Be more careful about echo_buf arithmetic, event-stream.c. src/ChangeLog addition: 2015-03-12 Aidan Kehoe <kehoea@parhasard.net> * event-stream.c (lookup_command_event): Check whether echo_buf_fill_pointer is negative before using it in arithmetic, avoiding a crash in GC. Oddly the old code didn't do this check and didn't crash, but its echo_buf was from malloced memory, not from our string data, so there may have been more room to manoeuvre.
