GCC generates two copies of the constructor. One is used to construct
whole objects; the other is used to construct not-in-charge virtual
base classes. You can find out more about this at
http://www.codesourcery.com/cxx-abi/ and in the C++ language standard,
if you're interested.

If I can find the time, I hope to get this fixed before the end of the
year.
