[SciPy-user] scipy.test problem

Hi,

Just to update on 64 bit, scipy tests.  I have now tested on two
identical 64 bit linux P4 systems:

1) Fedora core 4
gcc (GCC) 4.0.2 20051125 (Red Hat 4.0.2-8)
GNU Fortran (GCC 3.2.3 20030502 (Red Hat Linux 3.2.3-47.fc4))

2) Ubuntu
gcc (GCC) 4.0.2 20050808 (prerelease)
GNU Fortran (GCC) 3.4.5 20050809

Both have: nocona optimized atlas, fftw 3.1, numpy '0.9.7.2248', scipy
'0.4.7.1713'

System 1 generates error messages Hanno and I have reported for
scipy.linalg.test()

> FAIL: check_simple (scipy.linalg.decomp.test_decomp.test_eig)

System 2 passes all scipy.linalg.test()
Neither system generates an error for scipy.stats.test() - which
appears to be the source of the errors reported by Nils and Brett

Both systems hang indefinitely for:

scipy.lib.lapack.test()

I guess I'm going to conclude that

At least the combination of gcc 4.0.2 and g77 3.2.3 and ATLAS is not
compatible with linalg
At least the combination of ATLAS, gcc 4.0.2 and either version of g77
that I have is not going to work for lib.lapack
There is some other incompatibility for the setup of Nils and Brett.

Best,

Matthew
