Hello,<div><br></div><div>Nokogiri started working with MacRuby 0.8, which is awesome. However, I&#39;m getting sporadic crashes: &quot;incorrect checksum for freed object - object was probably modified after being freed.&quot;<div>
<div><br></div><div>It doesn&#39;t crash every time I run the test, but if I run it 10 times, I get one or more failures.</div><div><br></div><div><b>**Self-contained script to reproduce:**</b> <a href="https://gist.github.com/797346">https://gist.github.com/797346</a>.</div>

</div><div><br></div><div><br></div><div>I posted to the Nokogiri list (<a href="https://github.com/tenderlove/nokogiri/issues/issue/406">https://github.com/tenderlove/nokogiri/issues/issue/406</a>). The test case runs on all the other Ruby versions we&#39;ve tried, so it seems Macruby-specific.</div>
<div><br></div><div>Any insight appreciated!</div><div><br></div><div>Andre</div><div><br></div></div></div>
