I see lots of libmudflap FAIL on both targets though, is someone
working on those FAIL?
Uros looked at this for me and thinks it might be due to using an old
libc on the cfarm. I'll let him explain exactly what's needed.
For x86_64 I used debian 4.0 libc6 2.3.6.ds1-13 (I can update to
2.3.6.ds1-13etch5).
For x86 I used the much older ubuntu 5.10 libc6 2.3.5-1ubuntu12.
Kaveh did some debugging on a failed test to get:

Without knowing libc details I would say that 2.3.6 has a fatal bug
somewhere that was fixed in later versions.
