New Revision: 152822

URL: http://llvm.org/viewvc/llvm-project?rev=152822&view=rev
Log:
Add test case associated with:

    rdar://problem/11034702

For the time being, skip the relevant disassemble action which resulted in a crash.

Minor modification (print out format) to the existing TestDisassembleRawBytes.py test file.
