bug#11705: Strangest Emacs Bug I've ever seen

[Damian Kohlfeld]

This is a screen+emacs bug.  For whatever reason, it truncated "kbr" when
pasting into Emacs.

Been using Emacs Console for years (inside Screen).  I often copy/paste into
emacs buffer.

If I open emacs editor with:
Emacs test.pl

Then I paste the following text into the emacs console window:
eWRvbWFpbjCBnzANBgkqhkiG9w0BAQEFAAOBjQAwgYkCgYEAyZkbrbuq7a4Z1Ato

Only the following gets pasted:
eWRvbWFpbjCBnzANBgkqhkiG9w0BAQEFAAOBjQAwgYkCgYEAyZbuq7a4Z1Ato

I have tested this on emacs in Redhat 9, all the way up to emacs running on
CentOS 5.6

The same will happen with this text:
YEAyZkbrbuq7a4Z1Ato

The "kbr" gets truncated.

I've looked for control characters, etc, but have found nothing.  Here is a
block from Microsoft Notepad:

VQQDEw9Gb3J0LUZ1bnN0b24gQ0ExITAfBgkqhkiG9w0BCQEWEm1lQG15aG9zdC5t
eWRvbWFpbjCBnzANBgkqhkiG9w0BAQEFAAOBjQAwgYkCgYEAyZkbrbuq7a4Z1Ato
iPETp5Ds6OJWwsCGX5LK6FzDj7e8vA298OiXolOME2I9p7LvXtwUfFSCJH+VGWNE

If you paste that into emacs, the middle line is truncated.  

I do not even see how this is possible.  

Anyway, I thought I would let you know, I've definitely stumbled across
something very very strange.

Thanks for such an awesome editor, compiler, does-everything-I could ever
need program,,,

I can't reproduce this on Emacs 26.2 nor on current master.

Are you still seeing this bug?  If yes, could you please describe your
environment more precisely -- for example, what terminal emulator are
you using (xterm, rxvt, aterm)?  Can you paste this text line into other
programs running in terminal?  Can you paste it into emacs if you don't
use screen?

Thanks,

It's been 7 weeks without a reply from the original poster, which
makes it hard to make any further progress here.  I'm therefore
closing this bug.  If anyone can reproduce this, please reopen.
