We have a code example with a complex virtual inheritance hierarchy - it has
worked with previous gcc, 3.0 and above, but after installing Fedora the code
crashes. It appears that a pointer gets cleared for no apparent reason and this
causes the crash. We have managed to reproduce the crash with the short file
that I will attach.

Source file to recreate the bug
This works for me with 3.2.3, 3.3.3-pre, and 3.4 of last week. Maybe
someone with a debian box can verify.
Confirmed bug with stock 3.3.2 build. Must've been fixed since on branch and mainline.
