⁠R-devel SAN using Clang: R development binaries with Sanitizer support

The Writing R Extensions manual⁠ details in Section 4.3⁠ how to check memory access. Two sections are devoted to Using the Address Sanitizer⁠ and to Using the Undefined Behaviour Sanitizer⁠.

Both require a particularly instrumented binary of R. This repository provides a Docker container with such a binary, based on the R-devel sources.

This repository uses clang; a sibling repository⁠ uses gcc.

Note: This container must be run with docker run --cap-add SYS_PTRACE, otherwise instrumented processes fail to start due to lacking permissions. Alternatively, an instrumented process can be run with ASAN_OPTIONS=detect_leaks=0, but this turns off leak detection.

⁠Rocker-Org

This repository is part of Rocker-Org⁠ where Rocker⁠ -- Docker containers of interest for R users -- is being developed.

All this is work in progress; talk to @eddelbuettel and @cboettig about how to get involved.

Documentation is being added at the Rocker Wiki⁠.
