I can reproduce the error with this compiler:

Intel(R) C++ Compiler for 32-bit applications, Version 7.1   Build 20031225Z

But it works with this compiler:

Intel(R) C++ Compiler for 32-bit applications, Version 8.0   Build 20040122Z
Package ID: l_cc_pc_8.0.058_pe059

>>> import A
>>> import B
>>> B.Derived()
Base()
Derived()
<B.Derived object at 0x4035b504>
>>> <ctrl-d>
~Derived()
~Base()

I know cross-module inheritance works with Intel 7.1 for non-virtual classes. I
don't have any idea what to do about the failure for virtual classes. Can you
switch to the 8.0 compiler?

Ralf
