Follow-up Comment #12:

Then, I'm going to change the BISTs to use reproducible matrices and the LU
factorization. It is strange that using LU factorization or direct linear
system solution can lead to very different results, but this is not a problem
in eigs.
While trying to debug this, I noticed that LuAminusSigmaB in
liboctave/numeric/eigs-base.cc performs A-sigma*B even if sigma is zero. Is it
ok if I put that block inside a if (sigma != 0)?
