That is not what I was asking for. Please add -v to the command line
used to compile libavutil/crc.o and show its output.

When you use -mtune=native, please include output from "gcc -v ..."
to show real tune target passed to cc1. Otherwise, people will have
a hard time to reproduce your problem since their native machines may
be very different from yours.

This is only caused by -O3. -O2 seems perfectly fine.

Looks like caused by Sebs patches.  (I can't reproduce it though, maybe
re-verify with current trunk)
