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.

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 :/

But could you not replace -O2, for -O<something else> just on x86?
Yes, if it actually is only for x86 :/
Okay, now replacing -O2 with -O3 for x86 + GCC 4.1 systems for safety. Bumped to *.3-r1.
