Bug#711641: Octave crashes with message: "panic: Illegal instruction"

[Takashi Yano]

Package: libatlas3-base
Version: 3.8.4-9 (i386)

Octave crashes when using some linear algebra calculation.

Example:

octave:1> pinv(randn(2))
panic: Illegal instruction -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
Illegal instruction

If libatlas3-base package is removed, the problem does not
occur any more.

This seems to be the same problem with #635520, but
it must have been fixed in version 3.8.4-7.

My processor information is as follows.
