According to rakshasa and many others, rtorrent 0.6.3 crashes with [File chunk
read error: Cannot allocate memory] when compiled with gcc 4.1.x.
Since this is default compiler for many of us, rtorrent ebuilds should filter
-O2. Any other -Ox will work fine.
Details are here: http://libtorrent.rakshasa.no/ticket/495

I haven't applied this yet because there's something I cannot really grasp on
this issue. -Os is currently replaced by -O2, and here it works. It *might* be
an x86 specific issue, but I'm unable to find enough data about this :/

Then I guess we're stuck. I'm afraid I can't offer any more insight. I'm on x86
myself.
But could you not replace -O2, for -O<something else> just on x86?
