I haven't seen this one, but it looks like it dumps core after all of
the files have been copied.  This is probably in the remote_stubs
method in the install.rb.  Since this method prints a message after
the first declaration, the core dump is probably happening at this
part of the code:

  is_apparent_stub = lambda { |path|
    File.read(path, 40) =~ /^# This file was generated by RubyGems/ and
      File.readlines(path).size < 20
  }

This is probably where I would load up the core file in a debugger and
see exactly what it was doing when it crashed.  Looks like a good bug
report for ruby-core.
