I’ve written a ruby script that connects to a web service running  
within our intranet via Soap4r. I developed the script on a Mac (OS  
10.4.10, ruby 1.8.6 patch 0, soap4r 1.5.7, httpclient 2.1.0, net-ssh  
1.1.2) and I have no problems on my machine. However when we deploy  
the script to the production environment (a linux box with the same  
ruby version and gems as I have on my development machine), we get  
random segmentation faults:

/usr/local/lib/ruby/gems/1.8/gems/httpclient-2.1.0/lib/httpclient.rb:378  
: [BUG] Segmentation fault  
ruby 1.8.6 (2007-03-13) [i686-linux]

Aborted  
-bash-2.05b$ echo $?  
134

Here’s the code where the seg fault occurs:  
353 def load\_cacerts  
354 file = File.join(File.dirname( **FILE** ), ‘httpclient’,  
‘cacert.p7s’)  
355 if File.exist?(file)  
356 require ‘openssl’  
357 dist\_cert =\<\< **DIST\_CERT**  
…  
377\_\_DIST\_CERT\_\_  
378 p7 = OpenSSL::PKCS7.read\_smime(File.open(file) { |f| f.read })

The last line is where things die.

Has anyone else seen this problem? What version of OpenSSL should we  
be running for compatibility with Ruby’s OpenSSL library?

Any suggests on how to fix this would be much appreciated, since we  
can’t roll these scripts out with these errors.

Thank you,

Mark

You need to use the openssl version that matches with the openssl header  
files which are used when the ruby was compiled. Check the environment.

That doesn’t seem to be the problem. We’ve found that with OpenSSL  
0.9.7, we get random segmentation faults. If we upgrade to 0.9.8,  
they go away. In each case, we’ve rebuilt ruby so the headers always  
matched the library.
