Recent gcc and clang compiler versions provide functionality to memory violations and other undefined behaviour; this is often referred to as "Address Sanitizer" (or SAN) and "Undefined Behaviour Sanitizer" (UBSAN). The Writing R Extension manual describes this in some detail in Section 4.9. . This feature has to be enabled in the corresponding binary, eg in R, which is somewhat involved as it also required a current compiler toolchain which is not yet widely available, or in the case of Windows, not available at all (via the common Rtools mechanism). . As an alternative, the pre-built Docker containers available via the Docker Hub at https://registry.hub.docker.com/u/eddelbuettel/docker-debian-r/ can be used on Linux, and via boot2docker on Windows and OS X. . This package then provides a means of testing the compiler setup as the known code failures provides in the sample code here should be detected correctly, whereas a default build of R will let the package pass. . The code samples are based on the examples from the Address Sanitizer Wiki at https://code.google.com/p/address-sanitizer/wiki/AddressSanitizer.
