1.12 + *
1.13 + *
1.14 + *SUMMARY: Passing a RegExp object to a RegExp() constructor.
1.15 + *This test arose from Bugzilla bug 61266. The ECMA3 section is:
1.16 + *
1.17 + * 15.10.4.1 new RegExp(pattern, flags)
1.18 + *
1.19 + * If pattern is an object R whose [[Class]] property is "RegExp" and
1.20 + * flags is undefined, then let P be the pattern used to construct R
1.21 + * and let F be the flags used to construct R. If pattern is an object R
1.22 + * whose [[Class]] property is "RegExp" and flags is not undefined,
1.23 + * then throw a TypeError exception. Otherwise, let P be the empty string
1.24 + * if pattern is undefined and ToString(pattern) otherwise, and let F be
1.25 + * the empty string if flags is undefined and ToString(flags) otherwise.
1.26 + *
1.27 + *
1.28 + *The current test will check the second scenario outlined above:
1.29 + *
1.30 + * "pattern" is itself a RegExp object R
1.31 + * "flags" is NOT undefined
1.32 + *
1.33 + * This should throw an exception ... we test for this.
1.34 + *
