I got the same problem on a linux x86-64 1.9.2 build. It's absolutely weird, because the test code reads: do_check_eq(results.getValueAt(0), "senior citizen"); do_check_eq(results.getValueAt(1), "old but not senior"); It fails on the first of these 2 lines. But here are the things I tried and got me amazing results: - If I invert those two lines, the tests pass. - If I add a "dump(results);" before the first test, the tests pass. - Even better, if I add an empty commented line ("//") before the first test, the tests pass.
Three empty lines before the first test are also enough.
Running through valgrind makes it reliably pass, while running several times in a row makes it fail 80% of the time for me.

This is clearly a race condition, and it gets worse when JIT is enabled on x86-64.
Summary: test_autocomplete.js failures → test_autocomplete.js failures | old but not senior == senior citizen

My mistake, I see the race condition and I'll have a patch up in the next few days.
