This was found by the afl fuzzer http://lcamtuf.coredump.cx/afl/

$ echo | gsed -f afl-out/crashes/id*03,*
^C

$ cat afl-out/crashes/id*03,*
$G
$D


$ hexdump -C afl-out/crashes/id*03,*
00000000  24 47 0a 24 44 0a 0a 0a                           |$G.$D...|

or

echo | gsed -e '$G
> $D

^C

I ran the fuzzer and the test on NetBSD amd64 7.99.x.
