Since the day gcc-4.9.0 came out I am trying to get gcc compiled without

Where gcc-4.8.2 passes the tests, gcc-4.9.0 is failing - without
exception - every time on the next tests:

Frans.
I tried the same on a 32-bit machine, without these errors! On this
32-bit machine I got a lot of timeout errors for gcc-4.9.0 tests but not
the first errors.
@Bruce, so maybe it is timing. Maybe it is timing combined with the type
of processor. You use a i7 and I use an AMD Phenom II 965. Your SBU's
are also about 60% compared to my machine.
Let's hope that gcc-4.9.1 is more stable and less sensitive to timing
variations.
Regards, Frans.
