[Trilinos-Users] error in destroying ML preconditioner

[Kevin Long]

Hello,

I vaguely recall a recent question from a user about an error when cleaning up 
an ML preconditioner. Has anyone noticed such a problem, and if so, any 
suggestions for a fix?

After a recent pull (from the main development branch), I'm seeing a problem 
with cleaning up ML after a successful solve. Here's the error message. Any 
help would be appreciated.

Thanks,

Kevin
