 So, I have been trying to track down a crash in MacRuby for some time. The
 crash is inside of a priority queue program I wrote earlier this year for
 an artificial intelligence class. In MacRuby 0.4 the program was non-
 deterministic but would run. Under MacRuby 0.5 (trunk) it currently
 doesn't run at all, crashing instead.

 crash text:
 {{{
 126 jordan at thetourist ...tificial Intelligence/Assignment No.
 1/priority_queue_bug > ./search.cocoa -m -c a-star
 input_files/input13_7.txt
 uncaught Objective-C/C++ exception...
 terminate called after throwing an instance of
 'RoxorReturnFromBlockException*'
 zsh: abort      ./search.cocoa -m -c a-star input_files/input13_7.txt
 }}}

 The current search.cocoa file will only run under MacRuby, but it could
 probably be made to work on RubyCocoa.

 search.pqueue will work under Ruby 1.8.6 and Ruby 1.9, but crash with the
 same error under MacRuby.

 I originally wanted to narrow this down to a smaller, more management test
 case that could easily be turned into a test for MacRuby's test suite, but
 everything I try works as a small test even though the original larger
 program crashes.

 Since I have had no luck tracking this down for sometime I am just
 uploading it as a bug.
