I've checked the BLAS papers again[1] and you are right, we should be
catching the other errors like M<0 listed there. So we need to do two
things (i) add the checks for those errors and (ii) provide a way of
setting a custom cblas_xerbla function to avoid the hard-coded abort()
at least when using GSL CBLAS. Let me know if these are things you
could help with. Thanks.
