<div>I am attaching a small modification of the eptorsion1.c example that replicates the issue. It looks like this bug is triggered when the upper and lower bounds are equal on enough (10) degrees of freedom.</div>

I can share the details (installation + command line) for running it. But the ideal would be to reproduce this error with a Petsc example so it's easier for you to investigate. I looked for a bound constraint minimization problem with TAO and TS but I didn't
find it. What example could I use? </div>

<div>Okay, there is no sophisticated caching going on. So, first I would get it to fail on1 process. It should if it just depends on</div>

The error is raised in the middle of the computation after many successful calls of TAOSolve and TAO iterations. My guess is that TAO computes the preconditioner during its first iteration with all variables in the active set. But the preconditioner is never
updated when some variables are moved to the inactive set during the next TAO iterations. Am I right? Can you help me with that?</div>
