I have the latest version installed on a Netgear R7000.
ftp://ftp.dd-wrt.com/betas/2017/10-25-2017-r33607/netgear-r7000/netgear-r7000-webflash.bin

The web interface crashes on receiving input greater than 85 characters.

To replicate, navigate to Administration->Commands, and run...

to pass:
echo 6-----------------------------------------------------------------------------85

to fail:
echo 6------------------------------------------------------------------------------86

This issue does not affect Telnet/SSH. It only affects running commands via Administration-->Commands input box.

Something to do with HTML codes for the Web-GUI?

It's to do with the character buffer length in the firmware. It has been doubled in r33679.
