As described here:

I instrumented the call which causes the NULL pointer dereference. And sure
enough, I finally triggered the crash. Here is my output:


Triggered histogram crash!

I will now apply the patch you posted and see whether it also fixes the
problem. You can still use my dump output to verify whether your patch would
address this state.
