Hi, For other Fedora users that may be struggling with this too...
Fedora 28 introduced new hardening flags for compiled code (see [1]). Particularly, -D_GLIBCXX_ASSERTIONS is added to the default CXXFLAGS (verify the output of 'R CMD config CXXFLAGS'), which enables range checks for C++ arrays, vectors and strings. As a consequence, you may see the following after running 'R CMD check' on your package with C++ code: checking compiled code ... WARNING Found ‘abort’, possibly from ‘abort’ (C) Found ‘printf’, possibly from ‘printf’ (C) I'm not sure whether this is a false positive or not. Anyway, a quick workaround is to disable this flag by including -U_GLIBCXX_ASSERTIONS in your local Makevars.
