Python interpreter hangs

[Rolf Wester]

Hi,

when I'm running the script that is listed below on one of our DEC-Alpha
stations,
python hangs after the print statement in the function test0. The output
"sum = 125000.0"
is printed on the screen but the print statement at the end of the
script is not executed.
The process is not idle but is running and demands 100% of CPU-time.
Python does not react on Ctr C, I have to explicitely kill it. Curiously
this script
works on a NT-PC, on another DEC-Alpha station and it already worked on
the same
machine it's now hanging. This is probably a problem with the DEC-Alpha
station but  I
don't have any idea what the reasons could be.
Did anybody have a similar problem or  does anybody have an idea
concerning my problem?
I would be very appreciative for any help.
