my installed linux-headers is 2.6.39 and the error message is

if I try to run `make headers_install` in /usr/src/linux as root, I got the same Segamentation fault error.

All other packages are up to date.

Thanks in advance for any suggestions

It's hard to tell what exactly what is going wrong, but 'make headers_install' is definitely something you shouldn't have done.
sys-kernel/linux-headers are in portage for a reason, you know.
