Any known fix for it? No, I don't think there is any known fix for it. However, does this problem keep on and makes debugging impossible (i.e., after you "cont", does it keep stopping)? > thanks! > > Eric Hmm, are you doing debugging in SKAS or in TT mode? In the second case, then it can be a bug in the ptrace proxy (which has a big bug with some gdb releases >= 6.0). In the first case, maybe it's something I observed too (I'm not sure because I don't use a lot gdb with UML)... Better, I've observed breakpoints being *skipped* by gdb. -- Paolo Giarrusso, aka Blaisorblade Skype user "PaoloGiarrusso" Linux registered user n. 292729 http://www.user-mode-linux.org/~blaisorblade ------------------------------------------------------- This SF.Net email is sponsored by: NEC IT Guy Games.
