Hello I'm being affected by this bug in lenny, with libatlas3gf-base v3.6.0-22. It's making octave unusable for me -
gdb octave run octave:1> A=[2 4;3 1]; octave:2> b = [5;2]; octave:3> A\b Program received signal SIGILL, Illegal instruction. [Switching to Thread 0xb53cdab0 (LWP 2415)] 0xb5b0546e in ATL_diamax_xp1yp0aXbX () from /usr/lib/atlas/libblas.so.3gf (gdb) x/4xb 0xb5b0546e 0xb5b0546e <ATL_diamax_xp1yp0aXbX+366>: 0xdf 0xf1 0x77 0x0c A quick check in the latest Intel IA-32 instruction set manual (p3-366) shows that DF F1 is an FCOMIP instruction for the x87. A google search reveals this instruction was introduced in the Pentium Pro architecture.
