I can run the full test without a segfault, although I am only using the 
newcore (I get a segfault when I install newscipy and try to import scipy). I 
am using Gentoo on a Pentium4, with Python-2.4.2 and gcc-3.4.4. I built scipy 
against BLAS/LAPACK/ATLAS using the same site.cfg as I used to build 
scipy-0.3.2. It turns out that on my machine, signbit returns False for any 
negative number, not just -inf. Here is the output of system_info.py:
