I'm not entirely sure what the processor specs are, but I'm running this on a 64 bit system running RedHat 7 (??). I haven't had any issues prior to this due to a different platform.
This is the last thing to happen before the RelaxError:

One other question to ask here is what architecture are you running this
on. It isn't a powerpc based mac, an sgi or a sun by any chance? The
code in float.py has only been tested on intel based platforms (linux
x86 and windows) currently.....
