2317.0. "-F- internal TPU failure on V3.1 doing a char del" by XMAILR::BATOR () Wed Feb 26 1997 11:34

I found a repeatable tpu error doing a very simple edit. I have reduced
    it to a simple example shown below

On USTEST:: running VMS V6.2  (SEPS97)

Shareable base: 0004B000  Ident: DECTPU V3.1  1995-04-22 00:27
Updater base:   000D5E34  Ident: DECTPU V3.1  1995-04-22 00:27


It *also* fails on node MLOPCS:: running VMS V6.1

...      Ident is DECTPU V3.1  1995-03-09 01:50
...

try this simple example===>
!++ cut here +++
$create a.a
abc
def
abc
def

abc
ctl-Z
$
$create c.1
set keypad edt
ctl-Z
$
!++   cut here +++

$ edit/tpu/command=c.1 a.a
search for "abc"   (gold-pf3)
search again  (pf3)
search again (pf3)
search again  (pf3)   (now we're at bottom)
del-line  (pf4)   (now we're at an empty line; this is the key!!!
                  IF this (next to) last line HAD even 1 space, then works OK)
dele char   (rubout key next to +/=)   causes ==>
%tpu-f-failure, internal TPU failure detected at PC 00000000

This is the known bug in DECTPU V3.1, and fixed in DECTPU V3.2.
