New issue 3384 by [email protected]: `Function('/foo/x')` should throw
http://code.google.com/p/v8/issues/detail?id=3384
https://people.mozilla.org/~jorendorff/es6-draft.html#sec-primary-expression-regular-expression-literals-static-semantics-early-errors
says:
It is a Syntax Error if FlagText of RegularExpressionLiteral contains any
character other than "g", "i", "m", "u", or "y", or if it contains the
same character more than once.
So this is the desired behavior:
> Function('/foo/x')
SyntaxError: invalid regular expression flag x
> Function('/foo/gg')
SyntaxError: invalid regular expression flag x
However, V8 only throws when the function is called (i.e. it's not an early
error in V8).
Test case that should return 'PASS' but returns 'FAIL' on V8:
var result; try { Function('/foo/gg'); result = 'FAIL'; } catch
(exception) { result = 'PASS'; } result
