bug#69519: 1gb file too big for Emacs to handle?

Dear Emacs bug exterminators,

My problem persists.  I very strongly believe that I have an example of a
bug in Emacs.

I have previously reported this.  I got some advice.  It did not solve my
problem.

Today I got a new, much bigger and better Chromebook, again from Lenovo.
This
one cost me $300, but it has 8gb of core and tons more disk.

On my newest Chromebook I see the following:

> free
               total        used        free      shared  buff/cache
available
Mem:         6736092     1194036     4052888       52208     1489168
5542056
Swap:              0           0           0
>

I do not understand these things at all well, but it looks to me like I now
have 4gb of free space.

So I think it is fair for me to report my real problem, again, almost
exactly
as I did before.

The 1 gb file for which I give a url below does not seem to work in Emacs.

The file enumerates the primes below 10^9, so it would be very handy to
have around.

I can find the file, literally, into an Emacs buffer.

But then I cannot move to the bottom, i.e., using M->.  In fact, in the
attempt to
move to the bottom, things go so badly that Emacs freezes, and I
have to kill Emacs
by 'extraordinary measures'.

Is this file just too big for Emacs to handle?

Please, before you reply, fetch that file, find it literally, and see if
you can move to the bottom with M->.  I'd love to know whether you can do
that.

Thanks,

Bob

I enclose now the info that I believe you like to get with a bug report.
