[SciPy-dev] Scipy 0.4.8 segfaults on 64bit Linux (Ubuntu).

[Rudolph van der Merwe]

I compiled and installed the latest Numpy 0.9.6 and Scipy 0.4.8
without any trouble on a 64bit Ubuntu Linux server (AMD Opteron). When
I run the Scipy unit tests though, it crashes with the following error
message:

Don't worry about a warning regarding the number of bytes read.

What could possibly be the reason for the Segmentation Fault?
