+*SUMMARY: Passing a RegExp object to a RegExp() constructor. 
+*This test arose from Bugzilla bug 61266. The ECMA3 section is:       
+*
+*  15.10.4.1 new RegExp(pattern, flags)
+*
+*  If pattern is an object R whose [[Class]] property is "RegExp" and 
+*  flags is undefined, then let P be the pattern used to construct R 
+*  and let F be the flags used to construct R. If pattern is an object R
+*  whose [[Class]] property is "RegExp" and flags is not undefined, 
+*  then throw a TypeError exception. Otherwise, let P be the empty string  
+*  if pattern is undefined and ToString(pattern) otherwise, and let F be 
+*  the empty string if flags is undefined and ToString(flags) otherwise.
+*
+*
+*The current test will check the second scenario outlined above:
+*
+*   "pattern" is itself a RegExp object R
+*   "flags" is NOT undefined
+*
+* This should throw an exception ... we test for this.
+*
