Details

(Keywords: assertion, testcase)

The following testcase asserts on TI revision 23a746dac370 (run with -m -n -a),
tested on 64 bit:

function f(x) {return x;}
x = f(/abc/);
eval("this.__defineSetter__(\"x\", function(){}); x = 3;");
eval("var BUGNUMBER = 233483;");
We didn't mark properties as having been specially configured when they were redefined with getters or setters, so the SETGNAME in the eval blithely kept writing to the slot 'x' used to use.
