Description
matrix.test, kernel_pca.test, regression.test and svd.test fail when linking against libmkl.
For failure in matrix.test I've traced down the abortion to this function call in operator*=(const Matrix&)
gsl_blas_dgemm(CblasNoTrans, CblasNoTrans, 1.0, m_, other.m_, 0.0, blas_result_);
Is this a problem in yat, in libmkl's implementation of cblas or in GSL's wrapper around cblas, i.e., gsl_cblas* functions?

Replying to peter:
For regression.test I've traced the error to
gsl_multifit_linear
which is called inMultiDimensional::fit
, which in turn is called fromPolynomial::fit
.
And that function calls
gsl_linalg_SV_decomp_mod (A, QSI, Q, S, xt);
so this error is possibly the same as in SVD.

I no longer have access to the system on which the failure was detected.
For regression.test I've traced the error to
gsl_multifit_linear
which is called inMultiDimensional::fit
, which in turn is called fromPolynomial::fit
.
