New issue 2407 by [email protected]: Object.isFrozen() throws when called
on a function whose caller is strict
http://code.google.com/p/v8/issues/detail?id=2407
This code throws in Chrome and returns false in Safari and Firefox:
function nonStrict() { return Object.isFrozen(nonStrict) }
function strict() { "use strict"; return nonStrict() }
strict()
Chrome throws "TypeError: Illegal access to a strict mode caller function."
All three browsers (properly) throw that error in the following case:
function nonStrict() { return nonStrict.caller }
function strict() { "use strict"; return nonStrict() }
strict()
Presumably v8 fails the first test because it uses the same machinery
inside Object.isFrozen that it uses inside the "nonStrict.caller" get in
the second case.
