speakup locking box on latest linux 5.3.15-1

[Kirk Reiser]

Hello folks: It appears the bug that visited speakup back in late
August is back and active. In kernel version 5.3.15-1 built on
2019-12-07. It can very easily be reproduced by hitting the next-word
or previous-word functions quickly in series. In fact it is veryd
ifficult to not trigger the bug. This is in debian sid BTW. My
machines are amd64 based so I'm not sure if it's active on Intel
processors.
