Float32 capable VSTs not working

[rubenmedrano]

Gives an error with Float32 capable plugins (non doublé floating) :

Traceback (most recent call last):
   File "MainApp.py", line 814, in callback
     plugin.process([input_audio], [output_audio])
   File "build\bdist.win32\egg\pyvst\vstplugin.py", line 188, in process
     self.process_replacing(inputs, outputs)
   File "build\bdist.win32\egg\pyvst\vstplugin.py", line 178, in process_replacing
     self.__process_replacing(byref(self.__effect), float_input_pointers, float_output_pointers, len(inputs[0]))
 WindowsError: exception: access violation reading 0x00000000
 Press any key to continue . . .

It just works fine with plugins that works internally with float64 streams.
I am using Windows 10 x64 and Python 2.7 x32 with 32bit plugins.
