same assertion, essentially same test in js1_7/regress/regress-452703.js
regressed by http://hg.mozilla.org/mozilla-central/rev/186b4ce768ec (bug 459537).

Still crashing. "let" is not the culprit:
for(y in [0,1,2]) y = NaN;
Assertion failure: JSVAL_TAG(v) == JSVAL_STRING, at jstracer.cpp:1334

I think you should add these to the bottom of the test function, so the test doesn't pollute the global namespace and [].__proto__.
delete [].__proto__.u;
delete y;

I found another testcase that still triggers this assertion. See bug 461590.
