R devel - Jan 2014 - Passing a large array to .Call by reference

I need to pass a large array to my C function. I am using .Call(). I can clearly
see according to the memory consumption (reported by gc()) that the array is
duplicated. Is there a way to avoid this duplication and pass the array by
reference?

Staring at gc() is at approximate at best. 

R has memory profiling, see Writing R Extensions for how to use it.

There is no code in your post, so not much else I can comment on.
