[SciPy-user] scipy on old CPU crashes

sorry, but scipy-0.7.0b1-win32-superpack-python2.4.exe and
numpy-1.2.1-win32-superpack-python2.4.exe crash on my old pc too,
which uses duron 750MHz. So now I think it is not the problem with
non-sse/sse/sse2 instruction

is there any method to find out the real reason except to compile from
the source

thanx

(I know Duron is too old, but currently I don't have the money to buy
a new PC or even update it :( so bad)

[code]
from scipy.integrate import quad
print quad(lambda x:x, 1, 2)      #crash soon
[/code]
