While I understand the frustration with the fuzzer bug reports like this
I very much disagree with your statement about ethical and moral
responsibility.
The bug is in the code, it would have been there even if Wenqing Liu
didn't run the tool. We know there are bugs in the code we just don't
know where all of them are. Now, thanks to this report, we know a little
bit more about at least one of them. That's at least a little useful.
But you seem to argue that the reporter should put more work in, or not
bother at all.
That's wrong. Really, Wenqing Liu has no more ethical and moral
responsibility than you finding and fixing the problem regardless of the
bug report.
I think the frustration comes from the fact that it's potentially a lot
of work to untangle and fix the real problem and now when it is out
there we feel obligated to fix it. And while bug reports and tools
generating these can always be better and reporters can always be a bit
more active in narrowing the problem down, you're of course free to
ignore this until you, or anyone else, has a bit of spare time and
energy to investigate.
