Joseph,
Sorry, can't quote your message as whatever you used confused my mail
handler. (Maybe try text-only next time if you remeber? I have had this
before, albeit very rarely.)
But it is a good idea. Someone with a bit of time should sit down and could do
this as we now have C++11 / C++14 as
algrind with the command line:

Excellent call, as usual! Thanks for doing that.
R actually makes is so easy to run with valgrind by calling

Yep. That's where I started. I may make that a PR then.

I agree and believe I looked into it once before --
Simon,
Your Makevars [1] is very standard so I would suspect it may be the actions
setup for macOS. Rcpp is still used by a large number of packages all of
which appear to build just fine on macOS (as eg evidenced by the CRAN checks)
if and when everything is setup correctly.

Thanks for circling back! This was a pretty impressive thread as you got

Naeem,
I would simplify, simplify, simplify -- as 'Rcpp FAQ 7.31' reminds us all,
testing _equality_ of doubles is challenging anyway.
Besides, it may make sense to would ascertain first you get what you want in
_purely serial modes_ and then move to OpenMP.

The point of RMatrix and RVector in RcppParallel is to shield objects inside
the RcppParallel blocks using Intel TBB from any interaction with the outer R

Where they work, you should not use Rcpp's own NumericMatrix and a
