New description:
The following code will crash when I run it on my Mac Pro (8x2.26 GHz):
{{{
#!/usr/local/bin/macruby
class Foo
def doit
end
end
class Bar
def initialize
@foo = Foo.new
end
def step
100.times{ @foo.doit }
end
end
@bars = []
1000.times { @bars << Bar.new }
steps = Dispatch::Group.new
@bars.each do |bar|
Dispatch::Queue.concurrent.async(steps) { bar.step }
end
steps.wait
}}}
Commenting out the "@foo.doit" line prevents the crash.

Comment(by joshua.balla...@…):
Adding repetitions inside of "step" makes it crash more regularly.
