This has been happening since at least 4/21/2010. Sorry for the delay in triaging ...
No longer seeing this crash.
The test is still failing in Debug mode:
I'm going to add it back to test_expectations.txt

Oh, I think we just need to apply failing expectation for both release debug, we used to have crash expectation but I don't think that's right.
I don't see this test crashing on debug bots anymore.
