> It's clearly the shared ATLAS library of the binary distribution; if I
replace it with a "native" one (built on my machine, with Sage 4.7.1.rc2,
i.e. from the ATLAS 3.8.3.p16 spkg; GCC 4.5.1), the segfault also doesn't
occur.
Note that I was referring to the ''old, official 4.7'' binary
distribution; just saw
[http://boxen.math.washington.edu/home/vbraun/Sage/sage-4.7.1.rc2/dist/sage-4.7.1.rc2-fat-x86_64-Linux.tar.gz
the new one] (4.7.1.rc2, with the new ATLAS 3.8.4 spkg) Volker built, cf.
[http://groups.google.com/group/sage-devel/msg/327a64b22a33ad58 this post
on sage-devel]. (Note that the new one is compressed with GNU `zip`, and
hence fairly large, 613 MB -- just downloading it... :) )
