Error copying dynamic view on copy of memory pool

[bathmatt]

Question,
I assume you don't need to do anything special to copy dynamic views around? I have a class that has a dynamic view and a memory pool and I'm getting an error. Here is the traceback. Any ideas? I've ran this through valgrind and that changes the error to a big allocation. GUessing memory error, not sure where to look

I assume that this in current kokkos/master (a.k.a., trilinos/kokkos) ?
The memory pool has had a complete overhaul and DynamicView in kokkos/develop holds onto its (reference-counted) supporting memory pool. This should address the bug you logged.
Just need to promote the current kokkos/develop to kokkos/master, and trilinos/kokkos.

trilinos/develop
How long until you promote to trilinos
