Subject: Re: KASAN: stack-out-of-bounds Read in update_stack_state
Date: Fri, 20 Dec 2019 20:38:47 -0500 [thread overview]
Message-ID: <20191220203847.08267447@rorschach.local.home> (raw)
In-Reply-To: <000000000000a3c3ef059a1e4260@google.com>
What's the actual bug? "stack-out-of-bounds" is rather useless without
any actual output dump. But that's besides the point, this commit is
*extremely* unlikely to be the culprit.
