--- Comment #3 from Caitlin Potter <caitpotter88 at gmail.com> ---
The cause is pretty straight forward, when parsing the destructuring pattern, there's a SavePoint for each property in the object literal, when parsed in an expression context, and this happens for every ObjectLiteral/ArrayLiteral parsed in an AssignmentExpression context.

A fix that may work is re-organizing it to parse as an ObjectLiteral/ArrayLiteral first, and switch to destructuring mode only if followed by a "=".
