The attached test case (unpack, chdir and run main.js with -n -a -m) asserts on
TI tip (tested on 64 bit).
The interaction between AutoShapeRooters and the changes to JSObject::trace from bug 639235 can cause us to miss parts of the shape tree when tracing --- the shape rooter marks a single shape (but not its parents), then JSObject::trace stops when it sees that mark bit.

This is broken in TM too but will be fixed by bug 569422. The below cset is a spotfix making Shape::trace trace all parents.
