Well, this is considered experimental and known for its controversial results
(for example, see http://www.phoronix.com/scan.php?page=news_item&px=MTI5ODE).
I didn't make representative benchmarks; as for the crashes, code compiled with
'-O2 -flto' looks more stable than '-O3 -march=native -mtune=native' (YMMV).
After all, --enable-link-time-optimization is not enabled by default (and never
should be), users aren't enforced to enable it - so I don't see a problem here;
INSTALL may warn about potentially unstable results of using this option.
