GetCell has problem for Matlab R2012a 32bit, R2012a 64bit, R2013a 64bit in Windows 8

[GoogleCodeExporter]

What steps will reproduce the problem?
0. create a C# project named xxx
1. save a cell v into a mat file using Matlab of above versions
2. mxCellArray v = mxCellArray)mf.GetVariable("v");            
3. v.GetCell(0);
4. run the C# app and when it comes to the end, a window says xxx.exe has 
stopped working. A problem caused the program to stop working correctly. 
Windows will close the program and notify you if a solution is available.

What is the expected output? What do you see instead?
The program should terminate normally.

What version of the product are you using? On what operating system?
As in the title

Please provide any additional information below.

I have attached an example test file

If I comment this line in SafeArrayPtr.cs, the bug goes away:

matrix.mxDestroyArray(this.handle);

But I guess it is not so good...

I think I have figured out what happened. The SafeArrayPtr does have some 
problem for recursive data structures such as cell and struct. In 
ReleaseHandle(), mxDestroyArray is called, which is designed by *MATLAB* to 
deallocate memory in a recursive way. In contrary, in this code, mxDestroyArray 
is called at each time an element of the cell array is disposed, including the 
cell array itself. That causes the problem I reported.

I think the only way to resolve the problem is to free the memory manually.
