got it running under gdb cannot get it to segfault
Well, under gdb don’t run it with -d (it’s important because this can slow
down ruby) and try to press key very quickly.Apparently it’s easier to have a segfault with a “fast” PC (or you must
have a stupid PC like svg to see the problem :-))Guy Decoux
