New issue 3865 by joaebert: Hydrogen produces invalid code
https://code.google.com/p/v8/issues/detail?id=3865
I tested the following JavaScript code in D8 (latest commit today,
176b68d11a2b485d9568d2e7fd03e6ed7b67dd54) and I run into an exception when
code for "parse" is generated.
The output when running d8 with --trace_codegen shows:
[...]

Running the same file with --hydrogen_filter ~ will not throw the exception.
