Feature #405: ssl.rb:31: [BUG] Bus Error

Hello, what's that ssl.rb? Can we get one?

/usr/local/lib/ruby/1.8/openssl/ssl.rb:31: [BUG] Bus Error
ruby 1.8.7 (2008-06-20 patchlevel 22) [i686-darwin9.3.0]

i'm not the original reporter of the bug, but looks like i'm getting the same error when compiling routes in merb (the web app framework)

This bug still occurs on ruby-1.9.1-preview1 on OS X Leopard/Intel 32-bit.

$ ruby19 -v
ruby 1.9.1 (2008-10-28 revision 19983) [i386-darwin9.5.0]
$ uname -a

$ sudo port list openssl
openssl                        @0.9.8i         devel/openssl

Line 31 in question from ssl.rb is:

      DEFAULT_CERT_STORE = OpenSSL::X509::Store.new

Setting line 26 to:

   :verify_mode => OpenSSL::SSL::VERIFY_NONE,

and commenting out lines 31-35 avoids the problem with RubyGems, at least.

Previous backtrace was:

Do you have the following gems installed?

thin
eventmachine

If you do, try uninstalling them and see if things work.  It worked for me.

Removing

thin
eventmachine

Worked for me as well.
Thanks Chas.

why do thin and eventmachine affect rubygems here?  Have you tried the latest version of eventmachine?
Thanks.

Bug #1678 has an excellent description of the problem, including valgrind info.

He has a (probably not correct) work-around that will let people get work done.

re: why removing certain gems works?  Probably because it shifted memory locations around enough to allow the references be valid.

Ciao!

• Category set to ext

Removing eventmachine fixes the problem because eventmachine loads openssl.  If you don't load anything that uses openssl, then you won't see the problem.

I'm no expert with openssl, but you can see in code like this that it expects a NULL or a valid STACK:
http://openssl.sourcearchive.com/documentation/0.9.8g/ex__data_8c-source.html

Looking at the code, I don't see ruby setting the STACK on initialization (GetX509Store), so I figured it should be NULL.

In 1.9.1 this was fixed in r27064.

• Tracker changed from Bug to Feature
• Description updated (diff)

Seems r27064 has already been applied. Does this still occur?
