I suggest you rm -rf site-packages/matplotlib and
site-packages/numarray and your matplotlib build directory.  
Then do a clean install of both packages, matplotlib cvs and numarray
1.1.1 or cvs.  Then try again, being mindful of which backend you are
running under with -dSomeBackend and perhaps increasing the verbose
level.

Hello Perry,

true, this work as such but the crash is still there.

No, it does not plot interactively either.
If I run the script

    from matplotlib.matlab import *
    t=3Darange(0,10,0.1)
    x=3Dsin(t)
    plot(t,x)
    print "fisch"
    show()

I get the following output:

    voss@plonk [~/src/mpl/test] ./test.py --numarray  =20
    fisch
    Floating point exception

Thank you very much,
Jochen

Hello,

I tried to use matplotlib with numarray instead of numeric for the
first time, but it seems that it fails for me even for the simplest
examples.  For example the script

    from matplotlib.matlab import *
    from math import sin

    t=3Darange(0,10,0.1)
    x=3Dmap(lambda tt:sin(tt), t)
    plot(t,x)

    savefig("out.ps")

fails during the savefig call with a floating point exception.
Unfortunately there is no backtrace printed, so I have no idea where
exactly the problem lies.

Questions: Is there any easy way to get more information about where
the failure happens?  Is this specific problem known?

All the best,
Jochen
