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

| * Author: christine@netscape.com |
| * Date: 11 August 1998 |
| * REVISED: 04 February 2001 |
| * (changed the comma expressions from trivial to non-trivial) |
| * Author: pschwartau@netscape.com |
| * |
| * Brendan: "The test seemed to require something that ECMA does not |
| * guarantee, and that JS1.4 didn't either. For example, given |
| * |
| * dec2 = "function f2(){1,2}"; |
| * |
| * the engine is free to decompile a function object compiled from this source, |
| * via Function.prototype.toString(), into some other string that compiles to |
| * an equivalent function. The engine now eliminates the useless comma expression |
| * 1,2, giving function f2(){}. This should be legal by the testsuite's lights." |
