Cygwin objcopy crashed

[jianpingw]

Hi,

I used cygwin objcopy to redefine a symbol in an object file:

objcopy --redefine-sym _foo=_bar f1.obj

f1.obj is a object file generated by Mircosoft VC++ compiler.
objcopy crashed with this error message:

----------------------------------------------------------------------------
3 [main] objcopy 908 handle_exceptions: Exception:
STATUS_ACCESS_VIOLATION
6 [main] objcopy 908 open_stackdumpfile: Dumping stack trace to
objcopy.exe.stackdump
----------------------------------------------------------------------------

The objcopy supports:
objcopy: supported targets: pe-i386 pei-i386 elf32-i386 elf32-little
elf32-big srec symbolsrec tekhex binary ihex

Also, here is the output of objcopy --info:

BFD header file version 2.15.94 20041229
pe-i386
 (header little endian, data little endian)
  i386
pei-i386
 (header little endian, data little endian)
  i386

The OS is Windows XP Home.
Could anyone please help me on this?

Thanks
Jianping
