"Illegal instruction" crash on processors without SSE2

[Dmitry]

I am using Ubuntu 11.04 with libblas3gf 1.2-8.
In Octave, the following code:
    eig( rand( 3 ) )
causes crash with message "Illegal instruction". Expected behaviour: it should calculate eigenvalues of a random matrix.
gdb shows that libblas crashed:
===
Program received signal SIGILL, Illegal instruction.
0x0244890c in ATL_diamax_xp1yp0aXbX () from /usr/lib/libblas.so.3gf
(gdb) where
#0 0x0244890c in ATL_diamax_xp1yp0aXbX () from /usr/lib/libblas.so.3gf
#1 0x00000000 in ?? ()
===

My processor has no SSE2 support: (lines from /proc/cpuinfo)
model name : AMD Athlon(tm) XP 2500+

Hi DMitry,
  Could you try this on a newer version of Ubuntu; I notice that in 3.8.4-8ubuntu1 on Quantal the change the changelog says that at the 3.8.4.-7 level there is an entry: 'Force generic x86 CPU when building a non-custom package on an x86 arch' and a few other CPU check type comments; it sounds worth trying it.
