In addition to this post:
I would like to report that numpy-1.2.1 and scipy-0.7.0b1 crash on there
corresponding .test() scripts.
It is a windows XP machine with an Athlon XP 2200 processor (does have
SSE, doesn't have SSE2), using python 2.5.4.
I found out the hard way that at least "leastsq" from "scipy.optimize"
crashes. The windows crashreport points towards "_minpack.dll" if I
Digging into the problem, it turned out that both numpy and scipy crash
on there .test() scripts. Going back to numpy 1.2.0 and scipy-0.6.0-P3
solved the problem. I think it is a reasonable guess (but not more then
that) that is related to SSE(2) instrucions ( see link above ).
Unfortunately I didn't store any output of the test scripts, and since
it is a critical machine I cannot experiment to much anymore with
different versions. Still I hope that this report may help.
p.s. I'm a relatively new user and was confused by the 'superpack' name
in the download section. After getting familiar with the problems
described above I think I understand what it means now. Would it be a
good idea to put a small explanation what 'superpack' means on the
website (just before, or in the downoad section)?
