Possible bug in objdump?

[Unix User]

Hi,

While disassembling dhry11.c which is part of the
Dhrystone benchmarks version 1.1, objdump seems to
disassemble incorrectly. In particular, objdump deals
with the instructions "rep" and "movs" incorrectly. 

So, I run:
gcc -S dhry11.c -o dhry11.s
gcc -c dhry11.c -o dhry11.o
objdump -d --no-show-raw-insn -r -s dhry11.o >
dhry11.dis

Now, dhry11.s contains the lines:
rep
movsl

The corresponding instructions in the disassembly (in
dhry11.dis) is  emitted on one line as:
4c8:   repz movsl %ds:(%esi),%es:(%edi)

The other instructions are disassembled correctly. So,
my question is: Is this a known bug in objdump and are
there fixes for the bug?

I can include the source file, dhry11.c, if needed.

Thanks
