This is not just with this version , but any version I try. It would appear to be a gcc/clang issue, but not obvious how to work around it. All suggestions gratefully received. Happy to test potential solutions to get this working.

I cannot reproduce using latest ruby-build version and same version of macOS. There must be something additional installed on your system (such as MacPorts) that aborts the build process.

$ gcc --version

I'm going to close this since this is the wrong project to report these issues to. If you have more information, please report to https://github.com/sstephenson/ruby-build/issues
