MC crashes inside Docker container on Windows

[Der_Meister]

Steps to reproduce:

1. Install Windows Containers and Docker.

​https://msdn.microsoft.com/en-us/virtualization/windowscontainers/quick_start/quick_start_windows_10

2. Save following code block to Dockerfile:

# escape=`

FROM microsoft/windowsservercore
SHELL ["powershell"]

RUN $env:chocolateyUseWindowsCompression = 'false'; `
    iwr https://chocolatey.org/install.ps1 -UseBasicParsing | iex

RUN cinst mc -y

CMD C:\Program` Files` `(x86`)\Midnight` Commander\mc.exe

3. Build image.

docker build -t mctest .

4. Run the image:

docker run -it --rm mctest

Actual result:

Assertion Failed: vio.whandle, function vio_profile, file w32_slang.c, line 574.
ABNORMAL TERMINATION

Expected result:
MC starts normally.

It may be bug of the docker implementation, but I don't know how to debug mc and determine why it crashes.

Midnight Commander upstream does not support Windows (in any way other than running under Cygwin). Apparently, you are using an unofficial Windows port of an older version:

​https://sourceforge.net/projects/mcwin32/

You are getting an assertion failure in a file that doesn't even exist in upstream Midnight Commander, so please report Windows-specific bugs against this port instead.
