I don't think this is correct. You're showing the command "declare -F < file"
but declare -F doesn't read stdin at all.
unicorn:~$ declare -F
declare -f crawl
declare -f fput
declare -f git

*What* failure?

Without seeing what's actually in your MAPFILE array, it's hard to
understand what you're saying here. ^@ is how vim displays a NUL byte.
Are you simply trying to edit a binary file? That would very likely
give you some instances of ^@ on your screen, one for each NUL byte
in the currently-visible part of the file.
Also, your bug report doesn't include which version of bash you're
running.
Please tell us:
* Which version of bash.
* What's in the file you're using.
* The *exact* command you're running, including the filename.
* The actual output you get.
Please be sure to include "declare -p MAPFILE" to show the contents of
the array.
