I found that Rcpp packages compiled with -fsanitize=address frequently crash on OS-X. I cannot reproduce this problem on linux so perhaps I am not using asan correctly, or perhaps it is related to the fact that R for Mac has been compiled on osx 10.9 and I'm using 10.11. For regular C packages, asan on osx does seem to work as expected.
Here a minimal reproducible example: https://github.com/jeroenooms/asantest. It resizes a vector a few times and then crashes. It works fine if asan is commented out in the package Makevars.
