...s) do use the flag. This results in potential crashes on linux in situations like using embedded R in another application that happens to export a symbol named similarly to one defined in R's library, since the runtime linker substitutes the address of the wrong function into the library's CallEntries. Using -fvisibility=hidden or -Wl,-Bsymbolic[-functions] fixes this since then the addresses of functions in CallEntries are fixed at library build time, which is probably the intended behaviour. Here is a small example, using grDevices::colors. I compile it with gcc -O2 r.c -I/usr/include/R...
