During the maintenance period on Monday, 14 Oct 2024, all new projects will no longer create a container registry as part of the project area. Already existing projects will be unaffected at this time. Instead, users should utilize the official ORNL container registries at camden.ornl.gov (internal/moderate) and savannah.ornl.gov (external/low). Please see ORNL Today article for more info.

Also came from an unrelated discussion. ADIOS2 MPI_Comm_dup()s its communicators, but potentially too late to protect from the user doing stupid things.
The first commit adds a test that triggers it. The 2nd commit is the simple fix.
