Hello! Sorry for the delay, I was away for some days.
The initializer is due to an error - I tried to use a common pointer instead of the UniquePtr, and forgot to remove it. Unfortunately, removing it doesn’t fix the problem. No, I didn’t configure libMesh with --enable-unique-ptr. I exchanged the libMesh::UniquePtr<...> for a (deprecated) libMesh::AutoPtr<…>, just to test, but I still got the same error as before. I’ll recompile libMesh with this option, to see if it solves the problem. For what is worth, I’m using the 1.0.0pre version.
