[gentoo-hardened] Invalid opcode

This isn't really a hardened issue specifically, but since that's the
profile I'm running and this is the list that I'm already subscribed to,
thought I'd go ahead and post here. See if one of you folks can offer
some suggestions for me.
I have a old Pentium 4 machine with a fresh stable amd64 hardened
install that I am planning to use as a dedicated Asterisk server.
Everything seems fine with one exception. I cannot unmerge any
packages. Neither --depclean or -C will work. They both bomb out as
soon as the 5 second countdown starts. The message said Invalid
instruction and the syslog indicated it was in time.so
klogd: emerge[28440] trap invalid opcode ip:2612992f7ac sp:3bbcc5cea60
error:0 in time.so[2612992d000+4000]
Then as I was working on asterisk when I got to the point where I was
configuring voicemail and was trying to record the name from a phone
extension, asterisk crashed after starting the recording. It will limit
the length of the recording to just a few seconds, so the common factor
here seems to be related to counting seconds. Here is the message from
syslog about Asterisk.
klogd: asterisk[2794] trap invalid opcode ip:1bd2a5e33a sp:2bb49ccdeb0
error:0 in asterisk[1bd29a3000+202000]
I did some poking around with google and so far haven't come up with
anything too useful. I ran memtest86+ for around 11 hours and it didn't
come up with any errors. So, I'm thinking I've got something borked in
my USE flags or system config, but I really don't know what it could
be. The system seems stable and the problem isn't random. Anyone have
ideas on what I can try to get this resolved? Here is the cpuinfo in
case that is helpful.....
