It should be easy to run this workflow to reproduce:

on: [push]
jobs:
  build:
    if: true
    strategy:
      matrix:
        os: [ ubuntu-18.04 ]
        ruby: [ rbx-4.12 ]
    runs-on: ${{ matrix.os }}
    steps:
    - run: sudo apt-get update
    - run: sudo apt-get install ruby clang llvm

    - run: wget 'https://github.com/rubinius/rubinius/releases/download/v4.12/rubinius-4.12.tar.bz2'
    - run: tar xf rubinius-4.12.tar.bz2
    - run: ./build.sh --prefix=~/.rubies/${{ matrix.ruby }}
      working-directory: rubinius-4.12

    - name: Install Bundler if needed
      run: |
        if [ ! -e ~/.rubies/${{ matrix.ruby }}/bin/bundle ]; then
          export PATH="$HOME/.rubies/${{ matrix.ruby }}/bin:$PATH"
          gem install bundler -v '~> 1' --no-document
        fi
    - name: Basic test
      run: ~/.rubies/${{ matrix.ruby }}/bin/ruby --version
    - name: OpenSSL test
      run: ~/.rubies/${{ matrix.ruby }}/bin/ruby -ropen-uri -e 'puts open("https://rubygems.org/") { |f| f.read(2014) }'

Already-built versions for Ubuntu 18.04 might help here, although different system library versions might be problematic.
I noticed there are builds for 16.04 and 14.04 but not for 18.04.

@eregon I fixed some build issues on 18.04 so that building from a clone will work. I still need to fix building from a release tarball.

[brixen]

@eregon BTW, thanks for sharing the workflow, I should probably switch over to Actions from Travis.

The build seems to go further with 4.13, either building from the tarball or a git checkout, but eventually it hangs:

From bin/mspec:10: warning: Insecure world writable dir /home/runner in PATH, mode 040777 it looks like it hangs when starting specs, or they take a really long time (>50min)?

Is there a way to disable running tests/specs and just build / install?

[eregon]

OK, looking at build.sh and Makefile, I should be able to just do ./configure && make && make install. I'll try that.

[eregon]

It builds fine with ./configure && make && make install on Ubuntu 16.04 and 18.04.

EDIT: macOS-related stuff moved to #3830

[eregon]

I moved the macOS-related SEGv to a separate issue:
#3830

This issue can be closed, it builds fine on Ubuntu now with ./configure && make && make install.
