Segmentation fault in inflector.rb

Hi,
I have finally given up and am desperately hoping for some help. I have
developed rails using MySQL-5.0.20a-nt. The application run without any
problem in developement environment. Now unfortunately in production I
have MySQL-4.1.11. Same application I try to run in production (with
mysql 4.1.11) it crashes with the following error. I have no clue why it
is doing that. I have been searching for the answer without any luck. I
did install mysql.so from(http://rubyforge.org/frs/?group_id=477).
Then I got “The application has failed to start because LIBMYSQL.dll was
not found. Re-installing the application may fix this problem” so I have
copied the IBMYSQL.dll from mysql5.0/bin to WINDOWS/SYSTEM32 dir.

Error:
/ruby/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active_support/inflector.rb:160:
[BUG] Segmentation fault
ruby 1.8.4 (2005-12-24) [i386-mswin32]

The database schema is same as used in development. Any help will be
greatly appreciated.

Thanks
