The data does change, that's why. It is apparently initialized when the
shared lib is loaded, but since the shared libs is -Bsymbolic, it is the
initial variable in the shared lib which gets initialized, and its copy in
the main remain uninitialized. When a subclass in the main executable needs
to access the typeinfo it refers to the uninitilized copy and the prog
crashes.

I have included the test case for that. The class definition is in the DLL
and is stored under the variable __ti14ParentClassDll, it is this variable
that gets duplicated.
