--- Comment #1 from Anastasius Focht <focht at gmx.net> ---
Hello folks,

I can't reproduce the problem even with original Wine version anymore. No idea
what happened at that time, maybe I had a tainted tree or some special app.
It's unfortunate that I didn't include the the debuggee info (app name) in the
logs.

The referenced x64dbg snapshot isn't available anymore at github site so I took
one nearby from SourceForge:

https://sourceforge.net/projects/x64dbg/files/snapshots/snapshot_2018-02-14_22-42.zip/download

Looking at the original sources of 'devicenameresolver' module there was no
change for long time so I assume every snapshot from 2016 onwards contains the
same code.

Debugging x64dbg (64-bit app) itself with x64dbg:
