Bug #1227: [BUG] object allocation during garbage collection phase
http://redmine.ruby-lang.org/issues/show/1227

ruby -v: ruby 1.9.2dev (2009-02-28 trunk 22678) [x86_64-linux]

I'm trying to profile sections of a large application (taskjuggler) with ruby-prof. As soon as I hit the RubyProf.stop call, I get the attached error message. Since ruby-prof is using C code as well, this may be a ruby-prof issue, but could also be a generic ruby bug. ruby 1.9 and ruby-prof both from svn today. Enclosing the RubyProf.stop call with GC.en-/disabled calls is a workaround, but no long-term solution.

To reproduce:
get ruby 1.9 and ruby-prof from svn. get taskjuggler3 from git (commit eee3a2c6f0d559086f95bc2b02e54bdae337fd95) has the offending code.
git clone http://www.taskjuggler.org/git-repos/taskjuggler3.git
cd taskjuggler3
git checkout eee3a2c6f0d559086f95bc2b02e54bdae337fd9
cd lib; ruby taskjuggler3.rb ../examples/acso.tjp
