Hi Urs,
I have tried to reproduce your failures on QPC2 and SMSQmulator8, I can
report that on my Fujitsu H700 Core i7 620 laptop with 4Gb ram running
Ubuntu 15.10, I can not reproduce the freezing.
The common thing in your You Tube Videos is you are using a Windows
operating System.
If I can not get QPC2 and SMSQmulator to freeze then the fault lies on
the host operating system.
Can you try your tests using a Linux system running QPC2 under Wine. I
would think this will not fail.
Regards,
Derek

Hi QLers,
I’m between work and home and did find some time to make some short videos
about the freeze case. Here they are:
QL/E (v3.11, SMSQ/E v3.22, QPAC2 v4.02) freezes!
http://youtu.be/wcngRwkvc5w
QL/E (v3.11, SMSQ/E v3.22, SMSQmulator v2.12) freezes!
http://youtu.be/HZ9jj162UN4
QL/E (v3.11, SMSQ/E v3.22, QPAC2 v4.02) workaround prevents freeze!

QL/E (v3.11, SMSQ/E v3.22, QPAC2 v4.02) no freeze when QDT is disabled!

I’m posting this message with my iPhone and will reply to all your replies when
I will be using my home PC, but this can be later on this week.
QL forever!

Because we have a Windows Freeze case at work which is very hard to trace
and analyse (visitors of the ZX-TEAM meeting will know) I wanted to at least
catch the QL/E Freeze case.
Last Thursday I was repeatedly able to reproduce the freeze using my QL/E
v3.13 wip (work-in-progress). I then reduced the steps needed to get the
freeze. In the end I can say you can get the freeze when doing this
scenario:
1. Start QL/E (e.g. start QPC2.exe).
2. From now on do not use the mouse, do not use the mouse pointer.
3. After the BOOT sequence of QL/E is completed (SBASIC job 0 is minimised
as "System" in the button frame, wait until Photo QL has completed
displaying the QL collection photo) press <ALT>+<\> to pick "System".
4. Now that you see the BOOT process windows in the middle of the screen
press <ALT>+<F> to pick QPAC2 "Files".
5. Once QPAC2 "Files" is on screen press <F2> then <W> followed by <ENTER>
to choose the drive "WIN1_" as the Source Directory.
6. Now the QL/E system freezes!
Okay, I can reproduce it. But the crash happens in the screen driver.
The problem is that SMSQ/E does not have any kind of memory protection
and you're loading a quadrillion extensions at boot-time. Any one of
them could be responsible of corrupting the memory in a way that QPAC2
will crash later on without being at fault itself.
Trying to track down these kind of problems is a huge pain, not sure
if I can find the time to do so.
Cheers, Marcel
