+ *  File Name:          function-002.js
+ *  Description:
+ *
+ * http://scopus.mcom.com/bugsplat/show_bug.cgi?id=330462
+ * js> function f(a){var a,b;}
+ *
+ * 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."
