Backport #2597: Crash in p248 while installing gem

=begin
This crash isn't always reproducible, but it hits me several times. It's doesn't looks like other filled issues, but maybe it's related to #2557.
Also it seems to be p248 specific.

Can confirm this bug with p249.

[hvolkmer (Hendrik Volkmer)]

=begin
I can also confirm this in p249.

It doesn't occur if I use this:

require 'rubygems'
require 'activesupport'
ActiveSupport::Multibyte::UnicodeDatabase.new.codepoints

However if I require the file directly the error occurs:

require '/opt/gems/activesupport-2.3.3/lib/active_support/multibyte/unicode_database.rb'

ActiveSupport::Multibyte::UnicodeDatabase.new.codepoints

This is just to reproduce the bug. It occures in a test run where it suddenly kills the rails server (mongrel).

I get this behaviour in the latest official 1.8.7 p243 as well the latest trunk (p249). p174 is fine.

I also confirm this in p249. I tried installing it from the tar ball and using rvm, both same result:

~> rvm install readline ; rvm remove 1.8.7 ; rvm install 1.8.7 -C --with-readline-dir=$rvm_path/usr

~ > gem install chronic

I installed p174 instead now which seems to work fine so far.
