Hi Brent,

The variant at https://github.com/rocker-org/r-devel-san-clang was dormant for a while (first an error during R package build, later a missing package) and was just resurrected and builds again. And then there is of course Winston's 'sumo' container with several builds layerd into one. I use that too: https://github.com/wch/r-debug | I added -fsanitize=address to compiler and linker variables in the | Dockerfile.

So I recommend following the set that Brian Ripley has at https://www.stats.ox.ac.uk/pub/bdr/memtests/README.txt | Finally, the Docker file installs additional Debian object libraries and R | packages that I want to test. | | When the package build gets to testing whether the package can be | installed, an error message appears saying | | ==ASan runtime does not come first in initial library list; you should | either link runtime to your application or manually preload it with | LD_PRELOAD. | | For example, | | ESC[0mESC[91m** building package indices | ESC[0mESC[91m** installing vignettes | ESC[0mESC[91m** testing if installed package can be loaded from temporary | location | ESC[0m==684==ASan runtime does not come first in initial library list; you | should either link runtime to your application or manually preload it with | LD_PRELOAD. | ESC[91mERROR: loading failed | ESC[0mESC[91m* removing ‘/usr/local/lib/R/site-library/utf8’ | ESC[0mESC[91m* installing *source* package ‘isoband’ ... | ESC[0mESC[91m** package ‘isoband’ successfully unpacked and MD5 sums checked | ESC[0mESC[91m** using staged installation | ESC[0mESC[91m** libs | | I've tried preloading various libasan.so files that I find on the system | but the loader says that it cannot load them. Maybe try removing 'address' and see what happens? | My questions are | | 1. is it possible to build and install R and packages (in a container) with | the gcc address sanitizer enabled? Yes. The two Docker contains show how to. | 2. if it is, how do I do it? Follow the container recipe? Use the container? Eg I just pulled up the rocker/r-devel-san, giving 'bash' as the command / entry point, and (having mounted my local directory too) said 'RD CMD INSTALL digest_0.6.34.tar.gz'. That install the package under the instrumented R(-devel) version. Tests should now use SAN. I have fixed bugs that way. | 3. is this ld_preload message relevant? If so, to which file does it refer? | Is there an ASAN runtime library file that I need to specify, and if so, | what is the path to it? I think it is relevant but you must have ended up with a non-working combination. I no longer recall why I removed 'address'. It may have been something like this, or something else. `git blame` tells me I did so in 2018. It's been a while. As I said, these things _are_ finicky. So I recommend - starting from a known working container (see above) - establish a baseline by testing a package which has a _known_ true positive - for which I wrote a package: https://cran.r-project.org/package=sanitizers - given the baseline make the mods you want to make and re-test you still get the true positive Hope this helps, Dirk | I appreciate your consideration and assistance. | | Thank you. | Brent | | P.S.
