[Bug binutils/9961] New: objdump disassembles invalid i386 instruction a

Subject: [Bug binutils/9961] New: objdump disassembles invalid i386 instruction as valid
Date: 18 Mar 2009 01:11:37 -0000

I look at the line in disassembled code:
c7 2b 00 00 00 00            movl   $0x0,(%ebx)
This should be an invalid instruction.
Intel manual (253666.pdf/253667.pdf) only defines c7/0 for the first instruction
byte c7 and the above instruction would be c7/5.

I used objdump that is currently in FreeBSD-7.1-STABLE. So the version is a bit
older.
