* The cmp utility has the questionable feature of using mmap whendas2003-02-261-0/+21
| | | | | | | | | | | comparing regular files. Add a SIGSEGV handler to make its behavior less surprising when a read error occurs. The handler does not attempt to distinguish errors from file truncation, but anyone actively modifying a file while trying to compare it shouldn't even expect something sane to happen.
