Details

(Keywords: crash, testcase)

The following test case (run with "-n -m -a") crashes on TI tip (tested on 64
bit):

function outer_func(x)
{
    var y = "inner";
    new TestCase( SECTION, { SECTION: ++y }.SECTION[y.SECTION(this, "acc4", {})][ x < SECTION], 2222, x);
}
outer_func(1111);
I made a mistake with the test case reduction here, you still need the js reftests shell.js before the test case. Using ./js -n -m -a -f shell.js -f testcase.js should work.
We were looking at the known type tags of locals/etc. instead of type sets and could miss JSOP_INC* overflows that produced a double value.
