+Version 2.0 has a known issue: if you disassemble a buffer of instructions
+that having the first byte as a prefix (LOCK, REP, REPNE), and you only
+get 1 instruction (passing 1 as value for the 'count' argument count),
+then only the prefix will be returned as instruction.
+
+An work-around is to disassemble the whole buffer, then get out the first
+instruction, then this instruction would properly includes both prefix and
+the next instruction.
+
+This issue will be fixed in the next version.
