Created attachment 9252
  --> http://llvm.org/bugs/attachment.cgi?id=9252
Python script and sample c++ file, called with args "test.cpp Person"

Using the libclang python bindings on Windows 7 x64 results in a "WindowsError:
Exception: access violation writing 0x000000001D1B81A8"

I have tried using the attached script and c++ file with both 64 and 32 bit
python executables, with both 64 and 32 bit libclang.dll files, both dlls built
by Visual Studio.

Both the llvm trunk source, and the llvm 3.1 source have been tested. Both give
the same error, as stated above.

Attached is a zip file containing the python script and sample c++ file.
