Bug ID: 40156
           Summary: AutoWikiBrowser database scanner fails with "no access
                    to memory location"
           Product: Wine
           Version: 1.8
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

System.IO.__Error.WinIOError at System.Xml.XmlReader.ReadToFollowing

Running the AutoWikiBrowser database scanner fails with "no access to memory
location" normally within seconds of scan starting.

Occurs on wine wine-1.8.1 and wine-1.7.39

To reproduce: export WINEARCH=win32
winetricks -q msxml3 dotnet35 corefonts gdiplus riched20 ie6

[Probably only dotnet35 is required for this testing]

download AutoWikiBrowser from http://sourceforge.net/projects/autowikibrowser/
choose latest version (5.8.5.1 at time of writing).

unzip AutoWikiBrowser and run wine AutoWikiBrowser.exe

choose Tools -> Database scanner

download a wikipedia database dump file from https://dumps.wikimedia.org/

browse to the database XML file

search based on title contains 'foo' or other option. Press Start.

Wait for scan to progress. Scan normally fails within seconds with "no access
to memory location" error (stack trace relating to C# XML reader attached).

The problem only intermittently occurs on smaller XML dump files (e.g. < 100 MB
uncompressed) but always occurs on large XML files.

Above process works without error under Mono version 4 on same machine (using
50 GB English wikipedia XML dump file) and of course on native Windows.

Possible further information/speculation:

I have written a simple single threaded console only .NET 2 exe that works
under same wine setup without this error on same machine. So I suspect that the
issue may be to do with multithreading: the AutoWikiBrowser scanner is
multithreaded, versions of the test console exe I wrote failed with same error
if I added multithreading.

Could you please check if this issue already occurs with Staging versions? This
sounds a bit like an issue with write watches, which means it would be a
duplicate of an other bug.

I'm not 100% sure about wine staging as I've not used it before. What I did (as
using opensuse leap) is download wine 1.9.3 from
http://download.opensuse.org/repositories/Education/openSUSE_Leap_42.1/ which
at the time of writing is the latest version available. I then removed .wine/,
re-did winetricks, ran wineboot and then retested: no difference, still get
same "no access to memory location" error.

Retesting as after a couple of years there are newer wine versions:

wine 2.0.1 with winetricks dotnet20 => fail, same error as before
wine 2.0.1 with winetricks dotnet40 => fail, same error as before
wine 3.5 with winetricks dotnet40 => success, database scan completes without
error (Jan 2018 enwiki, ~60 GB XML).

So from my testing issue has been resolved at some point between wine 2.0.1 and
3.5, so thanks to wine team.
