>Description:
The amd64 disassembler in DDB is rather poor.  For instance, it does not
comprehend the REX prefix which is used on all 64-bit instructions.
They instead get decoded as "inc" and "dec".  This makes the
disassembly useless, and the debugger hard to use.

 Never mind.  It appears the CURRENT code is much improved.  I am a fool 
 and should have looked at it first.  Please close this bug, sorry for the 
 inconvenience.
