New issue 4146 by [email protected]: Passing a frozen regexp as the first
argument to str.replace does not throw
https://code.google.com/p/v8/issues/detail?id=4146
Version: 9633ebabd405c264d33f603f8798c31f59418dcd
OS: MacOS
Architecture: x64
What steps will reproduce the problem?
var regex = /0/g;
Object.freeze(regex);
var str = "abc000";
str.replace(regex, "o");
What is the expected output? TypeError exception thrown
What do you see instead? No exception.
The relevant spec bit is that
http://people.mozilla.org/~jorendorff/es6-draft.html#sec-regexp.prototype-@@replace
step 10c does a Set on the regexp with the "Throw" flag set to true, so an
exception should be thrown.
