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
Darwin mackenzie.local 9.5.0 Darwin Kernel Version 9.5.0: Wed Sep 3 11:29:43 PDT 2008; root:xnu-1228.7.58~1/RELEASE_I386 i386
$ 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.
=end

[expertseries (Matt Gardner)]

=begin
Removing

thin
eventmachine

Worked for me as well.
Thanks Chas.
=end

[rogerdpack (Roger Pack)]

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

=begin
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!

[docwhat (Christian Höltje)]

=begin
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.
=end

[docwhat (Christian Höltje)]

=begin
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.

[docwhat (Christian Höltje)]

=begin
In 1.9.1 this was fixed in r27064.

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