Hi
I'm seeing strange behaviour on an Array.prototype.slice.call starting
at r6096. That change was quite large so I haven't tracked down the
cause yet.
The user code is doing
Array.prototype.slice.call(arguments, 2)
where the length of arguments is 1. At r6096, the returned array has a
length of 17, with all values as null. Calling it as
Array.prototype.slice.call(arguments, 2, arguments.length)
works as expected (length 0), and it works properly <= r6095 either
way.
Unfortunately, the obvious test case does not exhibit the broken
behaviour, so I guess there's some bad stuff happening.
Any ideas on how to track down what's causing this? (I'm running via
d8).
