Fixed in git head, this should be backported to all active branches.

FYI, a comment form Laszlo Ersek in Red Hat BZ:
https://bugzilla.redhat.com/show_bug.cgi?id=794766#c8
The easiest fix would have been to restrict "nargs" to NL_ARGMAX.

This was posted in:
http://sourceware.org/ml/libc-alpha/2012-03/msg00101.html
Replies indicate it is preferred to limit nargs by available memory rather than
using an arbitrary limit, i.e. what Kees' patch was doing already.
