I have updated my package, rbedrock [1-2], to remove a bundled library's calls to abort() and stderr when compiled with -DNDEBUG (which is the default). This has mostly worked; however, I have uncovered that libc++ contains inline functions that call abort() if exceptions are disabled.
My bundled library is a C++ library and is compiled with exceptions turned off. I use its C-level interface in my package, so its C++ code is mostly hidden from my package. When compiled on a platform with libc++, libc++ introduces abort calls into the compiled package. This is causing `R CMD check` to warn about abort() usage on those platforms. I am wondering what people on this list think I should do? Should I enable exceptions in the bundled library and keep using the C-level interface? (It doesn't throw any exceptions itself, but std library calls might.) If there is any other strategy that I should try, please let me know.
