Use of Rcpp Module causes dangling pointers

[TobiasMadsen]

A well known problem with Rcpp Modules. http://lists.r-forge.r-project.org/pipermail/rcpp-devel/2014-June/007758.html

Easiest way to reproduce is:

• Create module
• Save Image
• Overwrite module
• Run garbage collection: gctorture()
• Load Image
• Call module function

E.g.

varDim <- 2
facPot <- list(matrix(0.5,1,2))
facNbs <- list(1)
mydfg <- dfg(varDim, facPot, facNbs)

save.image(".RData")

mydfg <- 2

gctorture()

load(".RData")

mydfg$dfgmodule$resetFactorPotentials( list(matrix(0.5,1,2)) )
