In my experiments with gcc 14.2.0-8 on Debian for amd64 (the debian:testing container), the warning only appears when all of the following flags are present: -fsanitize=address -O2 -Wstringop-truncation -Wall can be used instead of -Wstringop-truncation because the former includes the latter. -fsanitize=address,undefined also works, but not just -fsanitize=undefined. Remove the optimisation or the AddressSanitizer, and GCC stops being able to prove that truncation occurs. It looks like you will either need to find a container with R pre-built with sanitizers enabled (are there Rocker containers for aarch64?) or build R yourself [*]. -- Best regards, Ivan [*] https://cran.r-project.org/doc/manuals/R-exts.html#Using-Address-Sanitizer ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
