Hello,

I got a segmentation fault while trying to do a migration to a mysql database. I've tried versions 0.4.10 and 0.5.1 of the mysql2 gem. I have included my Gemfile, console output, and Diagnostic Reports file regarding the issue. If you have any suggestions that would be appreciated!

Thanks!

You'll probably want to build both ruby and the mysql2 gem with debug symbols in order to make a more useful bug report.
