Bug #5703: Ruby 1.9.3p0 segmentation fault (during autoload?)

I've been getting intermittent segfaults that appear to be coming out of autoload. Originally, I experienced them on 1.9.2p290, but they persisted after upgrading to 1.9.3p0. I thought the issue might have been #5047, but it seems not.

Here's an example:

/data/codeclimate/shared/bundled_gems/ruby/1.9.1/gems/mail-2.3.0/lib/mail/elements/content_type_element.rb:3: [BUG] Segmentation fault
ruby 1.9.3p0 (2011-10-30 revision 33570) [i686-linux]

c:0073 p:---- s:0307 b:0307 l:000306 d:000306 FINISH

Full output is at: https://raw.github.com/gist/5c7921f33908a3780779/d0f99051bda6f8cefbaf390ad54f13de09d24f5a/gistfile1.txt

The segfault occurs at different lines each time, but it always seems to be associated with loading new code (note rb_autoload_load in the C-level stack). The mail gem does not appear to have any C extensions, so I don't think it is an issue with that gem.

If more information is needed, I can try to collect, however it's fairly difficult because it occurs intermittently and in a daemon (Resque).

Any help would be appreciated.
