Segmentation fault with Ruby 1.8.6-p111 on 64bit Linux

I realize this isn't a Rails list but my problem is with Ruby as far
as I can tell.

I'm having issues getting a Rails app to run on a new 64bit Linux box.
The app has been working fine for some time on an older 32bit machine
that's being decommissioned soon.

Here's the error:

/usr/local/lib/ruby/1.8/pstore.rb:354: [BUG] Segmentation fault
ruby 1.8.6 (2007-09-24) [x86_64-linux]

It occurs on the first request to the Rails app, every time.

The Linux distro is RedHat 5. It came with Ruby 1.8.5. I compiled a
new 1.8.6-p111, reinstalled all the gems, but I'm still getting the
same error.

Anyone know how to fix this? 1.9?

Thanks,
