Well now I encounter:

/users/charlet/fsf/trunk/libsanitizer/sanitizer_common/sanitizer_linux.cc: In function '__sanitizer::uptr __sanitizer::internal_filesize(__sanitizer::fd_t)':
/users/charlet/fsf/trunk/libsanitizer/sanitizer_common/sanitizer_linux.cc:176:19: warning: 'st.stat::st_size' may be used uninitialized in this function [-Wmaybe-uninitialized]
   return (uptr)st.st_size;
                   ^

So I guess that's what we call "progress".

I'll keep using --disable-libsanitizer for the time being, this library is
clearly not quite productized yet IMO.
