I
I believe I have fixed this problem. I used a newer glibc version,
extracted it via cpio/rpm2cpio and it fixes it. It seems the version
of glibc that is installed with the fc6 port might have some
regression issues, I don't have a free machine to test my theory out.
I don't track the glibc changes, so it's rather difficult to say.
However, I think this change might have something to do with
(fixing?) the issue:

Anyway, here are some very brief instructions on how i fixed it:

"cd /compat/linux && fetch
ftp://rpmfind.net/linux/fedora/development/x86_64/os/Packages/glibc-2.7.90-7.i386.rpm"
Then you do a simple "rpm2cpio glibc-2.7.90-7.i386.rpm | cpio -idvu"
