Image used below compiles R-devel with gcc but uses clang11 for compiling packages.
Minimal example:
docker run -it registry.gitlab.com/jangorecki/dockerfiles/r-devel-clang Rscript -e 'install.packages("data.table"); readLines(system.file("cc", package="data.table")); library(data.table); example(fsort)'gdb info (do not just copy paste at once)
