Test common.decode x64 fails on Ubuntu 18.
The expected output seems to be different:
13: Testing nops 13: Done with nops 13: Testing SSE3 13: Bad instruction, instance 1 13: Testing 3D-Now 13: Bad instruction, instance 2 13: Testing far call/jmp 13: Bad instruction, instance 3 13: Bad instruction, instance 4 13: Bad instruction, instance 5 13: Bad instruction, instance 6 13: Access violation, instance 7 13: Access violation, instance 8 13: Testing rip-rel ind branch 13: Access violation, instance 9 13: Bad instruction, instance 10 13: All done
The "Access violation, instance 9" is unexpected.
