| 14 * causes an an assert on a null 'sprop' in the 'Variables' function in | |
| 15 * jsparse.c This will crash non-debug build. | |

| 20 * (changed the comma expressions from trivial to non-trivial) | |

| 23 * Brendan: "The test seemed to require something that ECMA does not | |
| 24 * guarantee, and that JS1.4 didn't either. For example, given | |
| 25 * | |
| 26 * dec2 = "function f2(){1,2}"; | |
| 27 * | |
| 28 * the engine is free to decompile a function object compiled from this source, | |
| 29 * via Function.prototype.toString(), into some other string that compiles to | |
| 30 * an equivalent function. The engine now eliminates the useless comma expression | |
| 31 * 1,2, giving function f2(){}. This should be legal by the testsuite's lights." | |
