Intermittent Seg fault when using net-ssh

Added by kimptoc (Chris Kimpton) over 12 years ago. Updated over 4 years ago.

Status:
Third Party's Issue
Target version:
-
ruby -v:
$ ruby -v ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin11.2.0]
Backport:
[ruby-core:40699]

Description

Hi,

This is probably a waste of a report - especially as my standalone 5 lines test of this generally works (it seg faulted once), but when run inside Rails3.1.1, via a background thread, if I use net-ssh, it crashes the VM.

$ ruby -v
ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin11.2.0]

On OSX 10.7.2

/Users/kimptoc/.rvm/gems/ruby-1.9.3-p0@p-viadropbox31/gems/net-ssh-2.2.1/lib/net/ssh/buffer.rb:255: [BUG] Segmentation fault
ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin11.2.0]

There's some chance that this is the same issue as:
http://bugs.ruby-lang.org/issues/4373

In which case it's not a Ruby issue, but a Macports issue. Follow these steps:
rvm remove 1.9.3
manually delete ~/.rvm/gems/ruby-1.9.3* (not sure how to make rvm do it automatically)
sudo port -fp uninstall --follow-dependents OpenSSL latest_version_here - note that this will delete everything that depends on OpenSSL, which is a lot (I'm now using homebrew for those things)

Now re-install ruby and your gems and it should work. I also added the following to my .bash_profile, not sure if it's needed:
export RUBYOPT="-ropenssl"

I do not know if just reinstalling ruby will be enough. I had seg faults with ruby 1.9.3p0, and i could fix it by following
http://www.christopherirish.com/2011/09/02/ruby-1-9-2-segmentation-fault-and-openssl/

What i've understood is that it was not an issue with MacPorts, but with Mac OS ssl which is still below version 1.0.0.
