Hello Stefan,

Thank you. I tested Cython-0.17b3 on Windows 7 with Visual Studio compilers.

32 bit Python 2.7 works well, only 4 test failures.

On 64 bit Python 2.7 and 3.2 with msvc9 compiler, python.exe crashes 
during `test_slice_assignment (memslice.__test__)`. I tested two 
computers. The Windows executive can not identify in which specific 
module it crashes, and neither enabling faulthandler nor building with 
debug symbols gives any useful information. Can anyone reproduce this? 
It seems compiler specific since Python 3.3, which is using msvc10, does 
not crash. When disabling test_slice_assignment, runtests.py completes 
with many failures.

The results of `runtests.py -v -v` are at 
<http://www.lfd.uci.edu/~gohlke/pythonlibs/tests/cython/>.
