[CLUE-Tech] Curious about GCC -O3

[Matt Gushee]

I have a question about the GCC optimization flags. I remember that
as recently as a couple of years ago, 'gcc -O3' was supposed to be
be buggy, thus -O2 was the most common setting on most or all Linux
distros. But I've gotten the impression more recently that -O3 is now
safe to use in most cases; at any rate, I now compile most applications
with -O3, and have not found it to cause any problems. So why is -O2
still the default?
