I have narrowed the issue down to a difference in behaviour between Windows and Wine.<div><br></div><div>The problem boils down to the following code:<div><pre style="font-family:Consolas;font-size:13;color:black;background:white;">

</div>To get a backtrace and be able to dump some datastructures, run with<br>
<br>
WINEDEBUG=+synchronous wine foo.exe<br>
<br>
This will bring it into the debugger once the condition happens.<br>
