Mark Thomas commented on DAEMON-402:
------------------------------------
Can you provide some more details about the circumstances under which you
observe these crashes?
To what extent has this patch been tested?
I am concerned that the patch is addressing a symptom rather than the root
cause.

> I see frequent crashes in prunsrv.exe on Windows 10.
> I have the impression that the WM_CLOSE windows message is sent multiple
> times - and the code does not expect that, resulting in an attempt to free
> memory that was already freed.
