> Here is a patch fixing the issue. I think that NULL check is needed here

In none of these three bug reports have you given an actual
bug report --- that is, there is no reason to believe that
these patches fix any reachable failure case.  If you have
examples showing that the cases are reachable, please
provide those first, and then we can discuss suitable fixes.
