Actually, showing up on one box but not another is strong evidence of a concurrency bug in my experience. Different<br>
cpu's at different speeds, with different speed memory and other side components change timings enough to expose bugs<br>
that otherwise haven't occurred elsewhere.<br></blockquote></div><br>Also, is there a way I can trigger the auto tester to run a few more times w/o committing anything? Everything passed on the latest run except Windows, which is broken for unrelated reasons, but I want to see whether I've solved the problem or the issue is non-deterministic and I just got lucky. (On FreeBSD everything started working after a change that shouldn't have mattered, but my gut feeling is that the failure here was due to a codegen bug.)<br>
