Default Converting from managed String to MFC CString

I have a managed app calling a C++ managed wrapper for a section of unmanaged C++ code which takes type CString as arguments.
When trying to convert from String to CString using a variety of methods the code keeps breaking on the following construct:

const __wchar_t __pin * strProduct2 = PtrToStringChars(strProduct);
CString strProduct3 = CString(strProduct2 );

Stepping in with the debugger leads to the line:

CStringData* pData = pStringMgr->GetNilString();

where the code breaks.

How does one convert a managed String into an unmanaged MFC/ATL 3.0 CString type?
