I can reproduce a crash with your sample program using the current numpy wheel
(1.9.2) and the python.org 3.4.3. The significant parts of the OS X crash dump:

So the crash is occurring as a result of a call from NumPy's _dotblas extension
module to OS X's libBLAS. There's nothing obvious here that would indicate
this is a problem in Python itself. Suggest you pursue this in the NumPy
community and, if necessary, open an issue there:
