User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/600.2.5 (KHTML, like Gecko) Version/8.0.2 Safari/600.2.5
Steps to reproduce:
http://jsfiddle.net/r3oycs9c/ (This works correctly in JSC, fails in V8 and SM)
Actual results:
SM will only produce a SyntaxError if the string appears to be an octal literal
Expected results:
SM should produce a SyntaxError for each tested case.
Reason:
There is no valid production for any numeric escape sequence that does not match `\ 0 [lookahead ∉ DecimalDigit]` --- \9 or \8 do not match CharacterEscapeSequence.
