Please keep the conversation on the bioc-devel mailing list, so that 
others can learn or help.

I use Linux, not Mac, but C (which I used to mean your C++ code) errors 
often occur on all platforms but are only visible as a segfault on one. 
I created the vignette R code with

   cd vignettes
   R CMD Stangle STAN-knitr.Rmd

This produces a file STAN-knitr.R. I then ran your R code with valgrind

   R -d valgrind -f STAN-knitr.R

this runs much slower than without valgrind. The first error reported by 
valgrind was

'Invalid write' suggests that you are writing after the end of memory 
that you'd allocated. I looked at the C code at the line where the error 
occurs as indicated in the stack trace, HMM.cpp:998 which is the 
assigment myStateBucks[i] = 0 in the loop

     int *myStateBuckets = (int*)malloc(sizeof(int)*ncores+1);
     for(i=0; i<=ncores; i++)
     {
         myStateBuckets[i] = 0;
     }

The argument to malloc (where he memory was allocated, at line 995) 
should be the number of bytes to allocate and it should have been memory 
for ncores + 1 'int'

   malloc(sizeof(int) * (ncores + 1))

rather than what you wrote, which is memory for ncores ints plus 1 byte.

C++ code would avoid the need for such explicit memory management, e.g., 
using a vector from the standard template library

   std::vector<int> myStateBuckets(ncores);

There were may other valgrind errors, but I do not know whether these 
are from similar programming errors, or a consequence of this one.
