Interesting. I just ran a test for a good bit longer, till it failed due to an nearing wraparound. Presumably because the crashes are too frequent to finish vacuuming. I did however, because Jeff said he coulnd't reproduce with cassert, use an optimized build. Wonder if there's some barrier related issue, making this dependant on the compiler's exact code generation. That'd explain why different people can reproduce it in different circumstances. Any chance you could package up that data directory for me to download?
