I could reproduce the crash with the current version of MC on RedHat Linux
7.1 with glibc-2.2.2 and kernel 2.4.7-ac2.  However, cp also crashes.  It
comes from fileutils-4.0.36.

I think that dumping the core on SIGXFSZ is a bug in glibc since mc never
changes the handler for that signal.  However, I don't know what POSIX
says about the default handler.

It should be possible to intersept SIGXFSZ in MC, but I doubt that many
users need it.
