Calculator reset glitch about epsilon

[artaxxx]

Thanks for your issue.
I can't reproduce the problem, could you please give me the version number you are using?
And maybe some pictures that illustrate the problem?

version 19.5.0 or 03.43 or bb3baa Serial number LwA1ABlRMTIwMzE0 FCC ID 2ALWP-N0110 I'm sorry that I cannot provide footage; but here is how I did it: go to the grapher plot the circle x^2+y^2=16 then go to the graph select navigate press left and back button in quick succession. It appears to only work some of the time; I reset my calculator using this glitch just now (I didn't record it; sorry), but couldn't do it again immediately after; My guess is that it has something to do with memory that accumulates with use/time; as I suggested on git hub; although I haven't looked deeply into the problem. I have also found this to happen a twice while running python programs on the calculator I will look into recording the glitch later thank you for your time

I am also experiencing this issue: Interrupting with the back button the plotting of functions that take a long time to plot abruptly resets the calculator on some quite rare occasions (with no apparent pattern for now). This might also be related to #1971 or #1970

I am too, but only with really large and big functions and then exactly the same as the others with the back button.
The reset is really much an issue, cause yeah I don't always backup my scripts all the time...
So please fix it!

I was able to reproduce the bug and I have a debug probe available, but can't really extract information when the crash occurs (don't have source maps or a way to compile the full firmware and rdp1 prevents me from debugging with SWD).

[Miniontoby]

Maybe it has to do with

The heap of the Python application has been increased to 64kB and the storage memory has been increased to 42kB.

and/or

Recursive calculations using Ans in the Calculation application are more efficient and lead to a memory full error less often.

from the version 19 update as listed in here: https://www.numworks.com/calculator/update/version-19/

Now with the version 20 I aint just yet able to reproduce the bug anymore.

I think this could be fixed now, but I am not sure. Please verify!

Not fixed yet: it happened to me a few hours ago, pressed the "back" button while it was rendering a graph, and it reset itself erasing everything.
Version 20.4.0

Version 20.4.0

I can't reproduce the bug. Can you give us the function entered?

I fear I cannot: it was an old function from a couple of sessions earlier, insofar as I can recall it was a third degree polynomial, nothing fancy, but I honestly don't think it's relevant. I can tell you what I was doing, anyway. I had switched the calculator off, without exiting the grapher app, then after a while I needed it and I switched it on again, a bit in a hurry, and as it started drawing I pressed the "back" button, possibly a couple of times. I was about to press the "app" button to exit the grapher app, but it reset all by itself. I'm sorry I can't be more specific...it was the second time it happened to me, and looks like some totally random bug.

About a third of the students in my class have encountered this bug, acting like you, but the bug is supposed to have been fixed by Epsilon version 20.3. 🤔

[artaxxx]

Indeed, this specific bug is supposed to be fixed in 20.3. If you find how to reproduce it, tell me!

Maybe like that @artaxxx 😀

Hello,
I can confirm this bug stills occurs on 20.4.0. It happened already 3 times on my son's calculator which was bought 10 days ago. He has a quite intensive use, though. And we unfortunately couldn't identify a clear reproduction scenario so far, just an intensive use...
