Floating Exception

[Jeremy]

Hi,

I just changed some previously-working Python program to add a C++ 
extension.

Now, when I call __init__() in a Python class I did not change and with the 
same arguments passed, I get the screen message 'Floating exception' and the 
program seems to stop. The exact point of the crash in __init__() seems to 
depend on from which directory I run the Python program.

What is wrong? And what is a floating exception?

Thanks,
Jeremy
