[Rd] Rprof(..., memory.profiling=TRUE) to profile C memory allocation?

[Henrik Bengtsson]

Could someone please confirm/refute that Rprof(...,
memory.profiling=TRUE) can also be used to profile memory allocation
done in a C function (src/*.c) that uses, e.g.

  allocVector(INTSXP, n)

but also allocations such as

 R_alloc(n, sizeof(int))

?

Modulo how R was built, does the answer depend on OS?  I'm interested
in all the major ones (Linux, OS X and Windows).

Thanks,

Henrik
