which commit fixed this crash bug? (reported on 2019-04-17)

[Christoph]

Hi,

back in April we reported a crash bug privately
via email to you (NLnetLabs).
You released the fix for it in 1.9.2.

Could you reference the commit id that fixed this
bug so we can try to get it backported to debian
where this crash still occurs because the fix hasn't
been backported yet?

thanks,
Christoph
