[SciPy-user] Problems with ACML

Hi,

Does anyone here use the AMD Core Math Libraries (ACML) as their
underlying libraries for BLAS/LAPACK/etc. in SciPy?  I have problems
with (at least) scipy.linalg.eigvals (Fernando discovered this at SciPy
on my laptop).  For instance, the following crashes reliably with ACML,
but works fine with ATLAS versions of BLAS/LAPACK:

>>>from scipy.linalg import eigvals
>>>from numpy.random import rand
>>>a = rand(100,100)
>>>eigvals(a)

Anyone else have this problem?  Is ACML known to be a bad thing to use
with SciPy?

Thanks,

Ryan
