---------------------------------
{code}
#include <iostream>
#include <vector>
int main()
{
std::vector<int>* vp = NULL;
if (vp == NULL && vp->size()) {
return 1;
}
return 0;
}
{code}
I use this code snippet to test, when compile with {{-Wnull-dereference}},
{{g++}} show this error.
{code}
g++: error: unrecognized command line option ‘-Wnull-dereference’

> Enable `-Wnull-dereference` when building Mesos

> Key: MESOS-4451
> URL: https://issues.apache.org/jira/browse/MESOS-4451
> Project: Mesos
> Issue Type: Task
> Components: build
> Reporter: Anand Mazumdar
> Priority: Minor
> Labels: mesosphere
>
> Currently we don't have {{-Wnull-dereference}} enabled for Mesos. This can
> sometimes lead to {{NULL}} dereference errors that go unnoticed like the one
> reported in {{MESOS-4449}}.
> We do have {{-Werror}} set to {{-Wall}} but this particular warning is not
> included in {{-Wall}}.
