the eigenvalue computation with SLECPc does not work with 2017.2 but converges for version 2017.1

reporter Yes, I can confirm this behaviour

It seems to me that removing
eigensolver.parameters["spectrum"]="smallest magnitude"
computation converges. Note that when using shift-invert we automatically obtain the smallest eigenvalues. Can someone confirm this behaviour ?
