I would be very surprised if that code have been touched in many years. More likely some corruption of the stack or some data structure. If the same code previously worked, then I'd still start by pointing at some shared library, but there might also be common data with other parts of RTPAD, which have been changed, while the RSTSRT piece was not.

Excellent. This is unscathed (ie. no patchin). The link date in the source
listing is: 29-JUN-2006 18:18
The only recent patch to RTPAD was in V7.3 for an unrelated problem.
BTW, I tried both 7.3 images too, and they do not work...

Yes, it comes from a V8.3 Alpha host with UPDATE-V0800 and SYS-V1000.

Linux speaks RTERM, not only CTERM?! :o
That would be an interesting solution. I didn't know at all that dnprogs now
support RTERM too, and I see that the author is you... :)
sethost.c, I suppose. At first sight the new dnlogin program appears not to
support RTERM. Am I right?

For what it's worth, both of the addresses I previously identified fell,

This module:

So, it makes come sense.

Probably not something I'd recomment... :-)
However, to comment the OP, it definitely sounds like some shared
library issue.
LIBRTL and LIBOTS see to be the only shared libs.

Hello all!
Let's try to summarize the problem.
RTPAD.EXE is the executable image behind SET HOST and SET HOST/APP=3DR on=
VMS,
and it can use both CTERM and RTERM protocols to connect to remote =
systems.
Some older OSes, notably TOPS-10 and RSTS (and others, I suppose), do =
either
behave badly when accessed with the newer CTERM protocol, mainly because =
it's
too VMS-centric, or do not work at all because they do not suppport it. =
To
connect to them, the solution is to always use the older RTERM protocol.
RTPAD.EXE on OpenVMS V8.3 for both Alpha and Itanium (IIRC) has some =
serious
bug that prevents it from connecting to such older OSes using the old =
RTERM
protocol: actually it ACCVIOs before doing any useful work.
The RTERM protocol can be used to connect to VMS too, and when connecting=
to
another VMS node using RTERM, the V8.3 RTPAD.EXE works as expected. So, =
either
some older OSes are sending out-of-standard packets (and the older =
RTPAD.EXE
were more forgiving), or the new RTPAD.EXE cannot understand all the =
protocol
variants and intricacies (as the older versions did).
I tried exchanging V8.3 RTPAD.EXE (ident X-10) with a couple of older =
versions
(idents X-8, X-9) and even with the V8.4 one (ident X-10 too, so should =
be the
same as V8.3), to no avail: every one of them ACCVIOs as well. The oldest=
I
tried (X-8) comes from plain vanilla V7.2 (and does not work), but I'm =
almost
sure (I cannot swear on it, though) that RTERM worked fine in V7.2, so =
I'm
stuck: the same image (X-8) was working on V7.2 but it's not in V8.3.

least
identify in which part of VMS lies the problem? Or give me some =
suggestions...
This is what happens:

This looks bad. I can tell you that it's not very likely a problem VMS address
which RTPAD is operating in. I suspect that 0000000000008AA4 would be close to
the PC in the RTPAD image or 0000000000052D8. I would guess that some improper
stack manipulation is the cause for this error.
If this stack dump came from V8.3, I'll take a look in the source to see if the
addresses yield anything. Please confirm that the above was from the Alpha V8.3
RTPAD.
