--- Comment #8 from paul at sketchfab.com ---
if it helps json parse error gives really strange token error reported:

SyntaxError: JSON Parse error: Unrecognized token 'ô'
SyntaxError: JSON Parse error: Unrecognized token '»'
SyntaxError: JSON Parse error: Unrecognized token 'Í'

amongst many other, which makes it looks like it reads out of bounds memory when parsing.

As it happens that we produce the json string from String.fromCharCode, slicde from uint8 array, and that it appends only on "big json" fails, it also point to that memory allocation/bounds problem.
