Problem with virtual inheritance and virtual functions

Thanks for your bug report. This is a known bug, and it is caused by
the -fvtable-thunks implementation. It does not occur when compiling
with -fno-vtable-thunks; unfortunately, you cannot do this on Linux
since it would require recompiling glibc as well.

I've been working on a patch for it for quite some time now; the most
recent version of this patch is in

http://gcc.gnu.org/ml/gcc-patches/2000-02/msg00934.html

That patch operates on top of 2.95.2 (actually, on the release branch
2.95.3); it does not work on top of the mainline compiler.

If you do test it, please let me know whether it works.

Regards,
Martin
