Bug ID: 54568
           Summary: Trying retrieve list of WMI classes makes powershell
                    core crash instantly
           Product: Wine
           Version: 8.2
          Hardware: x86-64
               URL: https://github.com/PowerShell/PowerShell/releases/down
                    load/v7.0.3/PowerShell-7.0.3-win-x64.msi
                OS: Linux
            Status: NEW
          Keywords: dotnet, download
          Severity: normal
          Priority: P2
         Component: wmi&wbemprox

Hi, trying code snippet below found on the internet (to retrieve all wmi
classes)  makes powershell core crash instantly.
$managementClass = New-Object System.Management.ManagementClass
$enumOptions = New-Object System.Management.EnumerationOptions
$enumOptions.EnumerateDeep = $true
$managementClass.PSBase.GetSubclasses( $enumOptions ) | Sort-Object
Maybe this is not yet supported in wine, but i guess it shouldn't crash
powershell  anyway. (Code snippet works fine in powershell core on windows)
From a debuglog:
 015c:trace:wbemprox:class_object_Get 000000001FB1DB70, L"__PATH", 0,

Steps to reproduce: - Save 4 lines of code above in e.g. a.ps1
                    -  wine pwsh -f a.ps1
Output from console:
Fatal error. System.AccessViolationException: Attempted to read or write
protect
ed memory. This is often an indication that other memory is corrupt.
