The bugreport.apple.com Problem ID is 7850167, originally filed in 11-Apr-2010
12:04 AM.
However, I don't think these are publicly visible, hence the link to the
discussion at macresearch.
I made yesterday a wrapper for the Apple BLAS and LAPACK. Today I have been
running tests. The complete BLAS test suite passes all tests, as does LAPACK
linear test suite. However, there are some failures (fails to pass, but does
not crash) in lapack eigenvalue tests. Many of these failures stay even when
testing against lapack 3.1.1 itself, without using the wrapper for Apple lapack
routines. Some failures were resolved by using blas from atlas.
So it seems there are some bugs left in the apple blas/lapack that are not
related to the function calling convention at all. With the wrapper these seem
to affect eigenvalue routines only.
