The test demonstrates a bad interaction between arguments object materialization, escape analysis and exception handling. We can return a wrong arguments object if we materialize arguments object (using f.arguments) and then throw around f's frame so that f does not clean up the materialized frame information (see the MaterializedObjectStore in deoptimizer.h/.cc). If we enter another function that has the same frame pointer and request an arguments object of (or lazily deoptimize) that function, we can get the materialized object of the original function. We should clean up the materialized object store when we unwind the stack. BUG=v8:3985 LOG=n Review URL: https://codereview.chromium.org/1032623003 Cr-Commit-Position: refs/heads/master@{#27406}
