Rails s return: [BUG] Segmentation fault

Question

If I run rails s, I get:

/Users/adam/.rvm/gems/ruby-1.9.3-p327/gems/pg-0.13.2/lib/pg_ext.bundle: [BUG] Segmentation fault
ruby 1.8.7 (2012-02-08

I had a similar problem, running anything with bundle exec gave a segmentation fault:

~/mayapp >bundle exec rake -T
/Users/rogermarlow/.rvm/gems/ruby-1.9.3-p327/gems/mysql2-0.3.11/lib/mysql2/mysql2.bundle: [BUG] Segmentation fault
ruby 1.8.7 (2012-02-08 patchlevel 358) [universal-darwin11.0]

Abort trap: 6

I had two problems (1) using 1.9.3p327 instead of 1.9.3p125 and (2) GEM_HOME environment variable pointing to a now non-existent directory. So the fix for me was:

~/myapp >rvm list

rvm rubies

=* ruby-1.9.3-p327 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

~/myapp >rvm install 1.9.3-p125
**snip**
~/myapp >rvm use 1.9.3-p125
Using /Users/rogermarlow/.rvm/gems/ruby-1.9.3-p125
Running /Users/rogermarlow/.rvm/hooks/after_use_maglev
~/myapp >echo $GEM_HOME
/Users/rogermarlow/.rvm/gems/ruby-1.9.3-p125
~/myapp ># you should check that the directory in $GEM_HOME exists, I had ...-p125@global which had been removed at some point
~/myapp >bundle install
**snip**

Now try that bundle exec which was segmentation faulting...

~/myapp >bundle exec rake -T
rake about                  # List versions of all Rails frameworks and the environment
rake assets:clean           # Remove compiled assets
rake assets:precompile      # Compile all the assets named in config.assets.precompile
