A package I recently had accepted to CRAN is throwing up a "memory not mapped" segfault on CRAN's post-acceptance fedora-clang ASAN test. This error does not occur with debian-clang or gcc. (Check results: https://cran.r-project.org/web/checks/check_results_TBRDist.html)
I found a similar issue in the r-packages archives ( https://stat.ethz.ch/pipermail/r-package-devel/2018q3/002907.html). The suggestion in that case was that the issue may have been a false positive, a possibility that is consistent with a "HINT" in the output log. I optimistically suspect that this is the case here too: my package is an R wrapper to a mature C library, and the segmentation fault arises during a routine operation with simple input, not in some obscure corner case. So question one is: how might I confirm that this is indeed a false positive? If it's not a false positive, then this raises the question of how I might reproduce it, as a Windows user without access to a machine running Fedora. rhub::check_with_sanitizers() uses debian, and returns 'success': https://builder.r-hub.io/status/TBRDist_1.0.0.9000.tar.gz-b965d74e18dd4bdc8e51e4254ee3699a Rocker (https://github.com/rocker-org/rocker) only offers a debian (not fedora) environment, so looks like it will not reproduce the error. Any thoughts would be gratefully received! Thanks, Martin -- *Dr. Martin R.
