There’s a new 3.0 version of ELFkickers available since may 2011, after a decade of inactivity.
You can read the changelog from the previous link to see what has changed, but concerning sstrip, the most important thing is that it now also works with 64-bit ELF files.
Let’s download, compile and install it:
$ wget http://www.muppetlabs.com/~breadbox/pub/software/ELFkickers-3.0.tar.gz $ tar xf ELFkickers-3.0.tar.gz $ cd ELFkickers-3.0/ $ make $ sudo make install
Now we can try it on strip 
First make a copy:
$ cp /usr/bin/strip /tmp/
Check the size before:
$ wc -c < /tmp/strip 220432
And also what file says before:
$ file /tmp/strip strip: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.26, BuildID[sha1]=0xa4aa26810da0b5672790975fc7e193520c9e2008, stripped
Now sstrip it!
$ sstrip /tmp/strip
This is the size after:
$ wc -c < /tmp/strip 218404
The size has been reduced by 2028 bytes:
$ echo $((220432 - 218404)) 2028
And here’s what file reports now:
$ file /tmp/strip strip: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), for GNU/Linux 2.6.26, dynamically linked (uses shared libs), corrupted section header size
file complains that the section header size is corrupted, but the sstripped binary still seems to run fine.
