I’m a greeen hand. I am learning ruby on rails by myself. However,  
when I was tring to create the first demo website following the book  
\<\<Agile\_Web\_Development\_With\_Rails\>\>, it reported that there was an  
bug[segment fault] in the file “mysql\_adapter.rb”.  
My OS:windows vista.  
database: is mysql 5.0  
rails: 2.0.2  
ruby: 1.8.6 [i386-minwin32]  
I used the command: “rails demo --database=mysql” to create the  
“website”  
And here is the original report:

* * *

[http://localhost:3000/](http://localhost:3000/) → /images/rails.png  
c:/ruby/lib/ruby/gems/1.8/gems/activerecord-2.0.2/lib/active\_record/  
connection\_a  
dapters/mysql\_adapter.rb:471: [BUG] Segmentation fault  
ruby 1.8.6 (2007-09-24) [i386-mswin32]

This application has requested the Runtime to terminate it in an  
unusual way.  
Please contact the application’s support team for more information.

It happened when i just click the title “About your application’s  
environment” in the web page"[http://localhost:3000](http://localhost:3000)"
