Invalid access to memory location

[Dick Monahan]

I just installed MySql. When I try to require it from Ruby, I get the following crash:

irb(main):001:0> require 'mysql'
LoadError: 998: Invalid access to memory location. - c:/Program Files/ruby/lib/ruby/gems/1.8/gems/mysql-2.7.3-mswin32/ext/mysql.so
from c:/Program Files/ruby/lib/ruby/gems/1.8/gems/mysql-2.7.3-mswin32/ext/mysql.so
from c:/Program Files/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:32:in `require'
from (irb):1
irb(main):002:0>

Here's the response from mysql -v:
