There is some piece of persistent state within the gatherScatter library that is not being handled properly, leading to cuda-memcheck reporting errors when the setup routines are called twice in the same program. @tcew and I discovered this while testing the spherical shell elliptic solver, where we ran into this issue when we tried to call ellipticSolveSetup() (which invokes the gatherScatter setup routines) twice.
