Comment:

 Thanks for the help Nick. I managed to compile Tor in 32-bit mode:

 {{{
 $ file src/or/tor
 src/or/tor: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV),
 dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.6.32,
 BuildID[sha1]=72f975f78f2ef98852368ebbe3a6205ddf0ea944, not stripped
 }}}

 I still have not managed to trigger this error unfortunately, even tho I
 compiled tor with `$ CFLAGS="-m32" ./configure --enable-gcc-warnings
 --disable-asciidoc --enable-expensive-hardening` and I checked that
 `src/ext/ed25519/donna/libed25519_donna.a` was built...

 Not sure what to do here. Anyone has tips on how to repro this?

 Otherwise, I just say we merge the patch since it just removes unused
 variables anyway (I checked all of them).
