August 24th, 2010 For a few months now, the bundler team has been getting intermittent reports of segfaults in C extensions that happen when using bundler with rvm. A cursory investigation revealed that the issue was that the C extensions were compiled for the wrong version of Ruby. For instance, we would get reports of segfaults in nokogiri when using Ruby 1.9 that resulted from the $GEM_HOME in Ruby 1.9 containing a .bundle file compiled for Ruby 1.8. http://yehudakatz.com/2010/08/24/a-tale-of-abort-traps-or-always-question-your-assumptions/
