349802 - "x;" (where x is a function) is eliminated only during second pass through decompilation due to {} block

Status: RESOLVED DUPLICATE of bug 349634

(Core :: JavaScript Engine, defect)

Description

[Jesse Ruderman]

> function () { { function x() { }; x; } }
function () { function x() { } x; }

> function () { function x() { } x; }
function () { function x() { } }

Expected: the "x;" statement should be eliminated on the first pass, or not at all.  My fuzzer in bug 349611 doesn't like it when functions change during a round-trip through uneval.

This might be related to bug 349634 (or it's possible that a fix for bug 349634 would mask this bug).

Just a dup -- loss of braces causes the rest according to correct optimizations.
