Fascinating.  The getrlimit kernel code should never return -EPERM, nor
lead to any selinux or apparmor calls fwiw.  I'd be curious to see an
strace of local.  If in fact a call to the kernel/sys.c:getrlimit() is
returning -EPERM, then the arguments passed to do_prlimit are being
corrupted along the way.

More likely would seem to be a problem with glibc.  We could try an
instrumented kernel to find out more.

Is this 32- or 64-bit?
