gcc b.c -Wall -O2 /usr/lib/atlas-base/libcblas.a /usr/lib/atlas-base/libatlas.a gcc b.c -Wall -O2 -lcblas causes the "Illegal instruction" abort in the execution. I have installed the packages libatlas3gf-base, libatlas-dev and libatlas-base-dev. My machine is a centrino laptop (first generation) with 1 GB of RAM. cat /proc/cpuinfo says: processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 7 model name : Intel(R) Pentium(R) M processor 1300MHz stepping : 5 flags : fpu vme de pse tsc msr mce cx8 sep mtrr pge mca cmov pat b21 mmxext mmx fxsr xmm sse2 b29 3dnow cpu MHz : 1294.75 bogomips : 1294.75 I found the original error compiling the latest version of GNU Octave and in the version of Octave in Debian GNU/kFreeBSD repos too. I reported the bug for the Octave package and Thomas Weber suspect a problem with ATLAS an the architecture.
