Hi Domenico,

Can you detail the exact command please ?

This is probably a misunderstanding rather than a bug.

The most likely cause is the choice of output directory.  Strip works by
creating a temporary file in the same directory as the output file.  It then
copies the input file into this temporary file, stripping it as it goes. 
Finally if everything has worked it deletes the output file and renames the
temporary file to the output file.  So if there is some reason why a new file
cannot be created in the output directory then strip will fail.  For example:

  strip foo -o /dev/null

Will fail because ordinary users cannot create files in /dev, and they cannot
delete /dev/null either.

Cheers
  Nick
