Comment:
I can reproduce it with sage-5.0.beta1 on Fedora 16. The problem is in
vector-matrix multiplication:
{{{
sage: vector(GF(3),[1]) * matrix(GF(3),[[]])
lda must be >= MAX(N,1): lda=0 N=0Parameter 7 to routine cblas_sgemv was
incorrect
}}}
Note that the matrix is of the wrong size, but the coercion model will try
it out to see if any error is raised.
