Hi Driller,

  I am unable to reproduce this problem. :-(

  Possibly the issue has been fixed by a recent update to the binutils.

  I did notice however that I was unable to run the command as you described:

    strip-new --strip-all -o /dev/null [poc_file]

  This always failed for me with the error message:

    strip-new: cannot create tempdir for archive copying (error: Permission
denied)

  This happens because objcopy tries to create a temporary file
  in the same directory as the output file (/dev in this case).
  Since normal users cannot create files in /dev the attempt fails
  and the error message is displayed.

  I worked around this problem by directing the output to a file
  in the current directory, like this:

     strip-new --strip-all -o delme [poc_file]

  With this change in place I was able to run the strip-new program on
  all 6 files in the zip archive and none of them triggered any problems
  with the address sanitizer.

Cheers
  Nick
