Attached file Testcase for shell
The attached testcase asserts on TI revision b8092cccaead (run with -j -m -n -a), tested on 64 bit.
Ow, really braindead bug introduced by one of the refactorings last month (replacing the jstype primitive with a Type class).  When testing an object Type for a particular primitive, the high bytes of the object would get truncated and could return a spurious match.
