FatalExecutionEngineError MessagePump() window close

Here is my code:
while (SFMLWin.IsOpened() && !OGREWin.IsClosed)
{
SFMLWin.CurrentView.Move(camera);
SFMLWin.DispatchEvents();
WindowEventUtilities.MessagePump();
if (globalPressed)
{
OnKeyHold();
}
MainDraw();
}
When I close the window, I get
FatalExecutionEngineError was detected

The runtime has encountered a fatal error. The address of the error was at 0x61696c9e, on thread 0x3018. The error code is 0xc0000005. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack.

I'm guessing this has something to do with closing the window. Any ideas?

are you using any worker threads that modify a mogre object?

Nope. That's essentially all of the code.

yeah, after closing the window, the control that mogre paints to is disposed. Another guess would be that mogre is trying to render to a disposed control after form closure. I have received that same error upon shutdown too but I can't remember what it was.

Well, there it is.

Bump:

So I know I posted this a while ago, but I have not found a solution (more specifically, I thought I found a solution but I didn't).

When this problem resurfaced again, I even forgot that I posted this and I ended up posting another topic. :/

But this is my main application loop:

while (SFMLWin.IsOpened() && !OGREWin.IsClosed)
{
try
{
if (fpsClock.Milliseconds > 0)
fps = 1000 / fpsClock.Milliseconds;
fpsClock.Reset();
SFMLWin.DispatchEvents();
SFMLWin.GetFrameTime();
inputKeyboard.Capture();
inputMouse.Capture();
OnCollision();
OnKeyHold();
MainDraw();
WindowEventUtilities.MessagePump();
}
catch
{
break;
}
}
SFMLWin.Dispose();
OGREWin.Dispose();

I am still getting the "FatalExecutionError" code when I close OGREWin at WindowEventUtilities.MessagePump();. The try/catch statement doesn't catch anything, and I can't implement any if statements around WindowEventUtilities.MessagePump() to fix the situation. This is a very urgent issue now, and I am really stumped on what to do.

Update:

I've posted this in StackOverflowe and got a response.

The native code is corrupting the garbage collected heap. Possibly due to a bad pinvoke declaration, but you'll have a heck of a time finding it. The place where it crashes is not the place where the damage is done. It is not a catchable exception in .NET 4, it is too severe a heart attack. Cut your losses if you can't get help from the authors. – Hans Passant

From this response, this means that it could me an error in MOGRE. Please advise.

Can you upload the project somewhere?

After stripping things out until something worked, I've discovered this:

SFMLWin = new SFML.Graphics.RenderWindow(hwnd);

The error only occurs when I have passed OGRE's window handle to SFML's Renderwindow, meaning when OGRE's window closes, WindowEventUtilities.MessagePump(); must have done something to the closed SFML window.

Is there any way to unbind SFML's renderwindow from OGREWin's handle?

I will also post something on the SFML Forums.
