It's not clear to me why you're implicating ping.  This looks like
something either from the library ld-2.13.so, or from the kernel about
that library.  I'm only guessing, but I would further guess that
"general protection" is part of the security apparatus that keeps
processes from interfering with eachother or with the kernel, and is
mediated by the hardware.

Good luck with that.  I suspect you'll need it.
