SUSE 8.1 linux
>Description:
When running the attached r shell file (compiling and executing some test c++ files), the dynamic_cast fails. All classes are polymorphic. When declaring and defining a constructor for D1, the cast works fine. When linking the modules directly insread of dlopen, the cast also works fine.
>How-To-Repeat:
Run the attached r shell file (tested on SUSE 8.1)
>Fix:
?
