Notes
[lenny] - webkit <no-dsa> (Unmaintained in Lenny, only affects fringe apps)
http://trac.webkit.org/changeset/64706
https://bugs.webkit.org/show_bug.cgi?id=43461
the problem is that the standard-library strtod()
parses "NAN(payload)" as a NaN with a user-defined payload, which is bad for the nan-boxing
scheme used by webkit (and mozilla). The fix is not to accept "NAN(payload)".
test-case: -parseFloat("NAN(ffffeeeeeff0f)")
reproduced with epiphany
