[PATCH] Keep the symlink target alive while realpath_rec reads it realpath_rec reads the names of a symlink target through a raw pointer into the string returned by rb_readlink, while it calls itself to resolve those names. RB_GC_GUARD(link_orig) keeps that string alive only for an absolute target. For a relative target, link_orig is Qnil and nothing uses `link` after the recursive call, so GC can free the string while the later names are still being read. File.realdirpath then returns a wrong path: the unresolved symlink path, or a path with NUL bytes, which makes Pathname.new raise "pathname contains null byte". CocoaPods calls Pathname#realdirpath for every source file, and pnpm installs packages behind relative symlinks, so `pod install` fails at random in such projects. File.realpath is not affected on platforms with realpath(3), because only RB_REALPATH_DIR uses realpath_rec there. Fixes [Bug #22479]
