dereferencing null

[Sandeep Datta]

I would recommend doing what Microsoft does in this case, use SEH
(Structured exception handling) on windows i.e. use OS facilities
to trap and convert hardware exceptions into software exceptions.

See the /EHa flag in the Microsoft C++ compiler.

I hope Linux has something similar, then we are all set!
