[hercules-390] HHCCP017I... Segmentation fault

[[e-mail] [hercules-390]]

Filtering with bing for 'hercules segmentation fault' I see that HHCCP017I pops up every now and then over the years. It is even solved here. https://github.com/hercules-390/hyperion/commit/ed1ff43b98bcb64796e92fcaa02c6a0b8afced14 (Alas for me with the given comments it is not obvious how.)
Toying arround with a Raspberry Pi I tested afore some Linux under VMware Player and got hit by HHCCP017I CPU0000: Machine check due to host error: Segmentation fault. The OS I took from Windows where it runs under Hercules 3.09 without show-stopping error.

What I tested so far:
CentOS 7 with Hercules 3.12 => works
Debian 8.7.1 with Hercules 3.07 => works

Lubuntu 17.04 with Hercules 3.12 => Seg. fault

The pragmatic solution would be, do not use Lubuntu. But my questions are, what caused this fault (or what cases exit by HHCCP017I) and who is host in this HHCCP017I info, the OS I try to run under Hercules or the OS that hosts Hercules?



BTW, the Hercules version distributed within Debian -- and so also in Raspbian on Raspberry Pi -- should IMHO stay 3.07, it seems to run faster than 3.12 (just a feeling, I did not measure it).


And -- are there alternatives to X3270? Or do I have to accustom me to it?



Ciao.....Mike

It is a segmentation fault in the host process running Hercules, not the
guest OS. The hardware being emulated by Hercules, the Hercules process
experienced the failure. Hence it is reported as a Machine Check
interruption to the guest. The "hardware", Hercules, broke.

This is triggered by the host operating system, a problem in the
compiled Hercules code or Hercules itself.

While the root causes of a segmentation fault may have parallels in a
Hercules guest, the term 'segmentation fault' itself is foreign to a
Hercules guest program.

In a Hercules guest such parallel causes would result in a program
interruption with an interruption code.

What about if the Hercules guest is z/Linux?
Does that have the concept or terminology
of "segmentation fault"?

Looking on the Download screen I cannot find :

Way back in the late '60s and '70s, it was recognized that JCL was a
very difficult language to learn and use, and needed extra facilities
such as PreProcessor Variable testing and arithmetic statements, the
ability to generate Control Cards with Symbolic Variable replacement,
easy to create full screen Panels, and primarily, an easy to use,
English like language using commands such as Copy, Print and so on.
Additionally, a really good macro language that would allow the
language to be expanded infinitely would be extremely useful.
The language was called Jol. Job Organisation Language.
Datamation ran a small article on it, and received 1000's of enquiries
- much more than they had received for any other product. In the early
'80s, IBM was about to sign a deal to market Jol - however a situation
developed much like Steve Jobs had in his company and so the deal was
not completed although Fujitsu and Amdahl supplied it with their machines
Decades have now passed, and while IBM has introduced some of the
features Jol had 40 years ago, many are still to come, such as an easy
to use English style language, full arithmetic expressions, the
ability to run the same scripts under TSO or Batch, and much, much more.
And so today, Jol is now under the Open Source banner. You are
encouraged use it for free, and the source code (which was examined
and approved by IBM in the '80s) is available with the proviso and
restriction that if it is turned into a commercial product, royalties
must be paid.
There are three or so versions of Jol.
1. The 370 Assembler Z/OS Mainframe version.
2. The Windows, Linux and OS/2 "C" versions that either generate code
that runs on the mainframe, or alternatively executes native
applications on their own platforms. The Linux version is in Beta mode.
3. A Beta version of a compatible IBM VSE version.
You can download Jol from the www.Oscar-Jol.com
<http://www.Oscar-Jol.com> site which also has all the documentation
and many examples.
Now, there is no reason why you cannot move to the next generation JCL
language.

i'm very new to this, but I've only seen that when Hercules isn't compiled with compression. Many of the distro-provided binaries don't seem to be.

I compiled Hercules only once - and failed. That was long ago, when Cygwin was a prerequisite for Hercules on Windows. Since then I use the compiled offers. If possible, I'll do so also in future.

When I have built hercules with optimization I get a wait state

My platform is windows I was using the intel compiler

I encountered a similar error while building Hercules from source on Linux. I tried turning the compiler optimization off when configuring and building it, and the problem went away- everything worked fine after that.
Sorry for not replying earlier, I have only just noticed this on Yahoo.
