Bug #5538: ruby memory error running minitests
http://redmine.ruby-lang.org/issues/5538

Author: Tom Macklin

Target version: 
ruby -v: ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin10.8.0], others


I have recently ported several applications from test-spec/ruby1.8.7 to minitest-spec/ruby1.9.2.  For one (and only one) of the applications, the test suite passes on ruby 1.8 and ruby 1.9.2p0, but crashes on my Mac, and also in other test scenarios.  Other tested scenarios:

Ruby 1.9.2p290, linux x86_64
Ruby 1.9.2p180, linux x86_64

Stack trace from my mac:

31 tests, 25 assertions, 0 failures, 0 errors, 2 skips

Test run options: --seed 42558

On Linux, we get a segmentation fault.  Please let me know if you want any more information.  I can get by with this problem as the code runs fine, and these tests work with 1.9.2p0.  

Thank you very much.
