[C++-sig] Getting base C++ class from a derived python class...

[Roman Sulzhyk]

Ooops, never mind guys, I thought it was the dangling pointer in the
casting of the Python class to base C++ class, but I've just realized
it was actually complaining about the next line, when it returns the
char * as the result of the testme() call, so I'm past the problem bit
and I'll be able to deal with it now.

Thanks, sorry...
