Ruby 1.8.7 Gem install Marshal.load error

[jadrevenge]

I'm really hoping that it's something stupid that I'm doing.

Ubuntu 17.10, fresh rvm install.

Description

"gem install bundler" fails under ruby-1.8.7. comes up with the message

ERROR: While executing gem ... (RuntimeError)
Marshal.load reentered at marshal_load

Steps to reproduce

1. install ruby-1.8.7-head
2. cd into directory that uses ruby-1.8.7-head in .ruby-version
3. "gem install bundler"

ERROR: While executing gem ... (RuntimeError)
Marshal.load reentered at marshal_load

Expected behaviour

bundler should be installed

This doesn't happen with ruby 1.9.3 on the same machine (different project) and doesn't go wrong on a machine that has this version of ruby installed on already:

chrisr@chrisr-Latitude-E6530:$ mkdir new
chrisr@chrisr-Latitude-E6530:$ echo "ruby-1.8.7-head" > new/.ruby-version
chrisr@chrisr-Latitude-E6530:$ echo "testme" > new/.ruby-gemset
chrisr@chrisr-Latitude-E6530:$ cd new
ruby-1.8.7-head - #gemset created /home/chrisr/.rvm/gems/ruby-1.8.7-head@testme
ruby-1.8.7-head - #generating testme wrappers..............
chrisr@chrisr-Latitude-E6530:~/new$ gem install bundler

Actual behaviour

jadams@EID-4546:$ mkdir new
jadams@EID-4546:$ echo "ruby-1.8.7-head" > new/.ruby-version
jadams@EID-4546:$ echo "testme" > new/.ruby-gemset

[jadrevenge]

I've got a fix of sorts ... but it's making my skin crawl.

I've added some versioning to the global.gems file for 1.8.7:

jadams@EID-4546:~$ more .rvm/gemsets/ruby/1.8.7/global.gems
gem-wrappers --force -v 1.2.7
rubygems-bundler -v 1.4.4
rake -v <10.2
rails -v 2.3.17
haml -v 3.1.7
rvm

then, once it's installed, and I'm in my project, I can sometimes get gem to install bundler ... (same command run 3 times in quick succession, with no other changes):

jadams@EID-4546:/ruby/loan$ gem install bundler -v 1.16.1
ERROR: While executing gem ... (RuntimeError)
Marshal.load reentered at marshal_load
jadams@EID-4546:/ruby/loan$ gem install bundler -v 1.16.1
Fetching: bundler-1.16.1.gem (100%)
ERROR: Error installing bundler:
invalid gem: not in gzip format in data.tar.gz
jadams@EID-4546:~/ruby/loan$ gem install bundler -v 1.16.1
Successfully installed bundler-1.16.1
1 gem installed

sometimes, changing my "rubygems" version to a newer version allows it to install, before I reset it back to 1.8.30.
