e.g. from ptrace, like Daniel said. I don't think it was from ptrace in the case where I saw a report, but it shows that the WARN_ON is bogus. If you really want to know what causes it you would need more debugging code as Nick pointed out too. So, the WARN_ON in its current form is known to trigger in a valid situation and not sufficient to find possible problems. I would remove it.
