* 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."
