Hi Sylvestre,
Can you explain your comment a bit; libblas for me is not a symlink; and as
for the low performance compilation; it seems to the opposite problem in this
case - it's trying to run a barcelona optimised version of the code that is
using an instruction not available on this cpu.

It is not about blas but atlas (libblas is just a symlink).
You should rebuild atlas for your system. By default, Debian (and therefor
Ubuntu) are shipping a low performance compilation of atlas.
You will find the information in the README.Debian file.
** Package changed: blas (Ubuntu) => atlas
It must be the same bug as reported there. I executed your commands and
it says "femms".
This is the output from /proc/cpuinfo
processor : 0
vendor_id : AuthenticAMD
cpu family : 20
model : 2
model name : AMD E-450 APU with Radeon(tm) HD Graphics

Interesting, I noticed bug 1122030 today - not sure if it's related.
Since you have it at a gdb, could you do:
x/i $pc
at the point it fails (possibly the disassemble command may work) to see
what the instruction is.
Also can you post the output of cat /proc/cpuinfo on your machine to
see wha
