(Many thanks to Sam James and Arsen Arsenović for the triage!) While we don't literally use -Werror, de-facto the result is the same: the package doesn't pass the check if the warning is emitted. The reason for that is that the "middle-end" warnings require optimisation to avoid false positives in the unreachable code paths, and sanitizers change optimisation too much for the warnings to remain reliable [2]. A similar false positive has been reported before [3]. Can we use -Wno-stringop-truncation during incoming checks with ASan? -- Best regards, Ivan [1] https://developers.redhat.com/blog/2019/03/13/understanding-gcc-warnings-part-2 [2] https://gcc.gnu.org/bugzilla/show_bug.cgi?id=117881 [3] https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108939 ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
