27	fold, foldSeg and scan fail to compile for tuple types	seanl	tmcdonell	"The fold.inl fails to compile when {{{TyOut}}} is a {{{struct}}}.
This is because the shared array {{{s_data}}} is declared with the {{{volatile}}} keyword to enable the warp level programming, and there is no copy constructor and no assignment operator defined for copying or assigning a value of the type {{{TyOut}}} to a variable of type {{{volatile TyOut}}}.

The following error messages are generated by nvcc.
