dynamic cast bug.

Thanks for your bug report. This is a known bug in the vtable-thunks
implementation; calling virtual functions in a constructor of a class
with virtual bases may result in incorrect `this' pointers. The bug is
Linux-specific in the sense that vtable thunks are used only on Linux;
it will be corrected in the new ABI of gcc 3.

I'm not sure what you meant when you said you tested it with gcc
2.95.3; there is no such release. The 2.95.3 mainline should have this
bug fixed.

Martin
