Since the day gcc-4.9.0 came out I am trying to get gcc compiled without
problems. That is working, by running the tests is a different story.
Where gcc-4.8.2 passes the tests, gcc-4.9.0 is failing - without
exception - every time on the next tests:

I am using a AMD64, 8GB system.
I have rebuild chapter 5 several times over, to the exact letter as in
the SVN docs. I did the same for chapter 6, up to gcc-4.9.0.
The report Bruce gave (24th) did not mentioned any failure in the gcc
tests. So, the question is what is going wrong?
