I'm getting a floating point exception in the eigen estimator for cheby on the 2nd solve of ex56 (you need to uncomment the define of TwoSolve) when I use sor PC (runex56 uses jacobi so you need to change that). I see this on Cray and my Mac.
I also found that the eigen estimator was called before the first solve, and worked fine, but I set the eigen values so I don't want it computing eigen values. I can understand cheby being the eager beaver and recomputing eigen values when I set a new matrix, but this not the semantics that I prefer. So there seem to be three issues: 1) seems the floating point exception. This only happens with a non-debug build. I'm also using 64 bit indices. 2) computing eigenvalues even though I set them. 3) I would like to tell cheby not to recompute eigenvalues. Mark
