I tried on GNU/Linux (in -nw) and on MS-Windows (in a GUI session), and both didn't trigger the assertion (tried with 3 executables, including those you mentioned). I'm guessing some particular byte sequence present in your binaries triggers this. So please provide more details. P.S. I frequently wonder why veteran experienced users omit crucial information from their bug reports, such as the C backtrace in this case, that is very easy for them to collect. Please don't ever assume that something which is 100% reproducible on your system can be similarly easily reproduced on any other system, and that therefore those details are an unnecessary luxury.

Package: Emacs
Version: 27.0.50
I can reproduce the above assertion failure when I do the following:
% src/emacs -Q /usr/bin/perl -l .../elpa/packages/nhexl-mode/nhexl-mode.el -f nhexl-mode --eval '(setq word-wrap t)'
y
M->
The `y` is because nhexl-mode prompts the user to convert the buffer
to unibyte and is not directly relevant: you can use find-file-literally
instead and the result is the same. I used /usr/bin/perl in the above
example, but I could reproduce the same crash with "any" binary
executable such as /bin/gzip and src/emacs (tho with some it doesn't
crash immediately).
Obviously, word-wrap in a binary buffer is not very meaningful, but
that doesn't justify a discrepancy between charpos and bytepos.
