[Rcpp-devel] Segfault error during simulation in Rcpp
Ok, I'll do exactly this and I'll report if I still encounter this problem in simpler programs. Thanks.

If you use any of the random number generators provided by R via Rcpp, then you __MUST__ also instantiate an RNGScope() object (which does this for you). We documented this *very* clearly in a number of places in the documentation. (And yes, sourceCpp() adds one as a courtesy but you should still add one. The extra few nanoseconds in execution speed won't matter.) You report is otherwise still unreproducible at my end. Your program is also complex in that it does a few things. Try writing smaller and smaller programs still exhibiting the error at your end. And do report back if you find something, or have questions.
