Comment #12 on issue 1942 by [email protected]: JavaScript Harmony freezes
Google Maps
https://code.google.com/p/v8/issues/detail?id=1942
I was tracking down a bug today and found this thread while searching for
similar error messages.
The error message was fairly strange to me: "SyntaxError: Identifier 'mb'
has already been declared". Strange because I don't usually see javascript
raise "Identifier" based exceptions.
Anyway, the bug ended up being a combination of Chrome's experimental
javascript flag being enabled, strict mode and duplicate function
declarations (2 customers raised bugs which surprised me given that a flag
was required).
While tracking it down took some time, a reduction is very easy to create:
"strict mode";
function foobar(){}
function foobar(){}
From reading MDN and the most recent ECMAScript Harmony proposal, this
doesn't seem to be correct for strict mode. Perhaps this is the same error
that Yehuda ran into?
