I thought I had already sent a message about this, but the error archive
doesn't show it.

There have been two errors found in 3.8.0, and errata fixing them have
been issued.  The most important error is:
   http://math-atlas.sourceforge.net/errata.html#RMAAT
This causes GEMM to compute the wrong answer for row-major C = alpha*A*A' or
C = alpha*A'*A.

The second error only effects configure on the Pentium-M, which is
misidentified as a CoreDuo.  The errata and fix are at:
   http://math-atlas.sourceforge.net/errata.html#PM-CD

Regards,
Clint
