I was attempting to push a new gem this evening and ruby 1.9.3 segfaulted. The dump indicated openssl and net/http as the issue.
Pushing gem to https://rubygems.org...
/Users/bjones/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/net/http.rb:799: [BUG] Segmentation fault
After a bit of googling I found a nice post describing how to resolve the issue.
The key part for me was adding –with-openssl-dir=/opt/local to the end of the command when running `rvm install ruby-1.9.3`.
