Problem
One of the tasks I'm working on requires developing native extensions. So for Ruby 1.8.7 I needed to install the various rake, rake-compiler, rspec and other gems for use under RVM. But when I tried to install them I had this error come up consistently:
mcpierce@mcpierce-laptop:ruby (Different-Runner-model) $ gem install rake
/home/mcpierce/.rvm/rubies/ruby-1.8.7-head/lib/ruby/1.8/timeout.rb:60: [BUG] Segmentation fault
ruby 1.8.7 (2012-06-10 patchlevel 368) [x86_64-linux]
Solution
I needed to reinstall Ruby 1.8.7 under RVM with the following compiler flags:
mcpierce@mcpierce-laptop:ruby (Different-Runner-model) $ CFLAGS="-O2 -fno-tree-dce -fno-optimize-sibling-calls" rvm install 1.8.7

Please be aware that you just installed a ruby that requires 2 patches just to be compiled on up to date linux system.
This may have known and unaccounted for security vulnerabilities.
Please consider upgrading to Ruby 1.9.3-125 which will have all of the latest security patches.
Once I did this then install gems installs worked as expected.
