ctypes Structures with c_uint32 bitfields have strange behaviour on OS X.

In the attached code when the field "number" is set, it changes the whole 32 bits, even thou its meant to be 23 bits.

The behavior is unexpected in:
OS X: Python 2.7.9

The behavior is as expected in the following environments:
Windows: python 2.7.9
Ubuntu: python 2.7.6
