[SciPy-Dev] scipy 0.9.0 scipy.test fails with segmentation fault
Wed Sep 21 06:34:40 CDT 2011
Thanks for the reply. I agree that I should take a look the BLAS library. I've only found one reference to this type of failure on the web, and it regards the use of Enthought Python....
This posting discusses a segmentation fault in the same routine, however with reference to the use of the MKL library. Something about the alignment of Fortran arrays being different in MKL.
Best regards -- David.

That test contains only pure-Python code, with some calls to BLAS.
Nobody has seen a crash at that point before, as far as I know.
I would try linking against the reference blas from netlib.org/blas, to check whether the BLAS libraries provided by RHEL are at fault.
