[SciPy-Dev] scipy 0.9.0 scipy.test fails with segmentation fault

[Baker D.J.]

Hello,

I'm building the latest numpy and scipy for one of the users here. The installation of numpy 1.6.1 looks good, however scipy 0.9.0 is not so great. I find that scipy.test(verbose=10) fails with a segmentation fault. Here's an extract from the typescript:

[root at blue33 ~]# python

etc, etc, etc
test_nonlin.TestJacobianDotSolve.test_broyden1 ... Segmentation fault

This is an "out of the box" installation. I'm working on a RHELS 5.3 machine, I use the GNU compilers ((GCC) 4.1.2) and the blas/lapack routines provided by the RHELS rpms. I could potentially switch to the Intel compilers and MKL, however I have many problems compiling numpy/scipy with the Intel compilers in the past. Is this a known problem and/or can anyone please advise me how to work around this problem? I would appreciate your advice, please.

Best regards - David.
