I've just found another solution: I've just changed my bzr to use 

void do_debug(const char *format, ...)
        va_start(ap, format);
        s = talloc_vasprintf(NULL, format, ap);

And now it seems to work fine, and I don't have to worry about va_copy 
compatibility any more... (talloc does it...)

[+ hopefully my bzr commits should be visible on samba-cvs soon...]
