*SUMMARY: Passing a RegExp object to a RegExp() constructor.
44
*This test arose from Bugzilla bug 61266. The ECMA3 section is:
46
* 15.10.4.1 new RegExp(pattern, flags)
48
* If pattern is an object R whose [[Class]] property is "RegExp" and
49
* flags is undefined, then let P be the pattern used to construct R
50
* and let F be the flags used to construct R. If pattern is an object R
51
* whose [[Class]] property is "RegExp" and flags is not undefined,
52
* then throw a TypeError exception. Otherwise, let P be the empty string
53
* if pattern is undefined and ToString(pattern) otherwise, and let F be
54
* the empty string if flags is undefined and ToString(flags) otherwise.
57
*The current test will check the first scenario outlined above:
59
* "pattern" is itself a RegExp object R
60
* "flags" is undefined
62
* We check that a new RegExp object obj2 defined from these parameters
63
* is morally the same as the original RegExp object obj1. Of course, they
64
* can't be equal as objects - so we check their enumerable properties...
66
* In this test, the initial RegExp obj1 will include a flag. The flags
67
* parameter for obj2 will be undefined in the sense of not being provided.
