Every time a program crashes, a crash log file is generated in ~/Library/Logs/CrashReporter (look for a macruby file there with the appropriate time stamp). 

Otherwise, since the crashing line seems to be

/Library/Frameworks/MacRuby.framework/Versions/0.6/usr/bin/macruby -w -Ilib:bin:test:. -e 'require "rubygems"; require "test/unit"; require "test/test_mysql.rb"' -- 

You can try

gdb --args /Library/Frameworks/MacRuby.framework/Versions/0.6/usr/bin/macruby -w  ...

Then inside gdb, hit 'r', then when it crashes, type 'thread apply all bt'.

A good thing to do in order to know if it's a GC problem is to set the GC_DISABLE environment variable to something and try again.

'set env GC_DISABLE 1' then 'r' again.

If you can attach that information to a new ticket I will have a look Monday.

Also, I would try if normal mysql-ruby scripts are working too. Maybe the test suite is doing a corner-case thing.
