How to fix the Ruby 1.9 HTTPS/Bundler segmentation fault on OS X Lion

By Hongli Lai on May 9th, 2012

If you’ve installed a gem bundle on OS X Lion the past few weeks then you may have seen the dreaded “[BUG] Segmentation fault” error, where Ruby sees to crash in the connect C function in http.rb. Upgrading to the latest Ruby 1.9.3 version (p194) doesn’t seem to help. Luckily someone has found a solution for this problem.

It turns out the segmentation fault is caused by an incompatibility between MacPort’s OpenSSL and RVM. MacPorts installs everything to /opt/local but RVM does not look for OpenSSL in /opt/local. We solved the problem by reinstalling Ruby 1.9.3 with the MacPorts OpenSSL, as follows.

First edit $HOME/.rvmrc and add:

export CFLAGS="-O2 -arch x86_64"
export LDFLAGS="-L/opt/local/lib"
export CPPFLAGS="-I/opt/local/include"

Then run:

sudo port install libyaml
rvm reinstall ruby-1.9.3 --with-openssl-dir=/opt/local --with-opt-dir=/opt/local

    I’m surprised someone chooses to still use MacPorts over Homebrew, it is just too good to pass up imo 😉

    Thanks for the hint, hopefully it will help someone else.

  • I ran into this problem several months ago and switched to Homebrew to resolve it. I understand MacPorts’s effort to minimize compatibility issues by installing its own dependencies, but sometimes (as here), it creates more problems.

  • We actually went back to MacPorts from Homebrew as we just found it easier to use. On that particular problem we however still have issues. After issuing the commands, we got the following error:

    ShishBook :: ~ » sudo port install libyaml
    Warning: xcodebuild exists but failed to execute
    Warning: port definitions are more than two weeks old, consider using selfupdate
    Warning: Xcode does not appear to be installed; most ports will likely fail to build.

  • Will this happen if I am using rbenv and brew? -Thanks.

    The following fixed it for me using rbenv and macports:

    CONFIGURE_OPTS=’–with-openssl-dir=/opt/local –with-opt-dir=/opt/local’ rbenv install 1.9.3-p194
