Hi everyone

I downloaded the Sage 4.5.3 source, compiled everything and ran a
doctest (./sage -testall) immediately afterwards. I guess everything
should run smoothly, but surprisingly, there were two failures:

Can anyone explain this? Should there be created Tracs for fixing it,
or am I missing something?
I am running Ubuntu 10.4, 64bit on a Thinkpad t410 with Intel i7
quadcore processor.

Cheers, Johan
