[Rcpp-devel] RcppArmadillo Memory Leak?

You don't mention how you're determining the size of the rsession
process, but you shouldn't necessarily expect it to decrease after
calling gc() - there may be memory fragmentation, but also the OS is
lazy about reclaiming memory from processes, so it may only be
returned to the OS when it actually needs it.
