DTrace disables destructive actions by default, and I do not activate them. Maybe some timing-sensitive code in the flash-player which does not handle the case that some parts can take longer than expected? I assume there is not bug in DTrace itself. There could be a bug in my patch, but I would assume it is not a heisen-bug as described here (the probes are handled by DTrace-macros, just the variables which are provided to D scripts are different from other probes).
