José,

I thought I'd try out the examples that you provide in
xtl-1.3/examples/tests.

Did you realise that only the raw tests succeed on an Alpha
machine? (Running LinuxAlpha.)

Printing out the stats by uncommenting the code in
main.cpp, we get for example:

aleem@acinus:~/xtl-1.3/examples/tests$ oxdr
Testing oxdr: Failed

Moreover, running this test preoduces the following in /var/log/kern.log:
