When I run rcov on small projects it manages to end, but on medium/big Rails projects it crashes with the following errors: $ rcov --version rcov 0.8.1.2 2007-11-22 federico@korobushka ~/programacion/vom $ ruby -v ruby 1.8.6 (2008-08-11 patchlevel 287) [i686-darwin9.4.0] federico@korobushka ~/programacion/vom $ rake spec:rcov (in /Users/federico/programacion/vom) ........................................................................................................................ ........................................................................................................................ ....../usr/local/lib/ruby/gems/1.8/gems/activesupport-2.1.0/lib/active_support/inflector.rb:283: [BUG] rb_gc_mark(): unknown data type 0x31(0x2521720) non object ruby 1.8.6 (2008-08-11) [i686-darwin9.4.0] $ rake spec:rcov --trace (in /Users/federico/programacion/vom) ** Invoke spec:rcov (first_time) ** Invoke spec:clobber_rcov (first_time) ** Execute spec:clobber_rcov ** Execute spec:rcov ........................................................................................................................ ........................................................................................................................ ....../usr/local/lib/ruby/1.8/timeout.rb:53: [BUG] rb_gc_mark(): unknown data type 0x31(0x2521720) non object ruby 1.8.6 (2008-08-11) [i686-darwin9.4.0] rake aborted!

Date: 2008-08-29 15:07 Sender: Tom Copeland Cool, thanks for confirming! I still wonder how that problem is happening... seems like that struct is getting created with a bad array size. Should dig some more.... but nice to have it working in the meantime...
Date: 2008-08-29 15:00 Sender: Federico Builes Tom: That last patch seems to fix it, thanks! Let's hope Mauricio can take a look at it.
Date: 2008-08-29 02:33 Sender: Tom Copeland OK, here's a slightly better patch that checks for buffer overruns: http://tomcopeland.blogs.com/juniordeveloper/2008/08/rcov-crashin g-w.html Still not perfect, but better, I think...
Date: 2008-08-26 02:07 Sender: Tom Copeland Hi Federico - Hmmm.... good point, I didn't run the tests after making that change.... hm. I'll see if I can do that. Thanks, tom
Date: 2008-08-25 21:57 Sender: Federico Builes Tom: Thanks for the suggestion. Sadly, removing that line breaks 3 of rcov tests and it produces bogus information on the final report (reporting lines as untested and stuff that doesn't appear when running rcov on each file).
Date: 2008-08-25 21:46 Sender: Tom Copeland FWIW, I found a sorta/kinda "fix" for it, details here: http://tomcopeland.blogs.com/juniordeveloper/2008/08/rcov-crashin g-w.html
