Welcome! Thanks for submitting your first AmigaGPT issue! Your issue will be looked at ASAP. <3

Sorry about that, I didn't set the stack size in AmigaGPT's .info file to the recommended 32768 bytes. I will fix that in the next version. In the meantime, you can easily fix this by selecting AmigaGPT's icon, then in the right click menu, go to the Icons menu then select Information. In the information panel select the Icon tab then set the stack to 32768 bytes. When you hit save it will use this new stack size from now on.

[gustavosarmento]

Tried your solution, but unfortunately the error message persists.

[sacredbanana]

If you go back to the information panel again, does it still show 32768?

Does the warning message always report your stack to be 8192 bytes?

Another thing you can try is in your Prefs folder, open Workbench prefs and set stack size in there to 32kb or higher

[gustavosarmento]

Yes, 32768 if coming back to the Information panel.

The warning message always reports that my stack is 8192 bytes (only once it reported 8448 bytes, but I couldn't reproduce it since), and my Workbench Prefs was originally set to a 4 KB stack (this being the default, I assume). Setting it to 32 KB or more doesn't change the error.

[sacredbanana]

what about if you execute it via the Shell before typing in the command STACK 32768?

[gustavosarmento]

...then it runs with no warnings.

[sacredbanana]

Ok odd. For some reason your workbench is both ignoring the icon stack size and also the internal stack cookie. Have you updated your AmigaOS with the 2 update files to AmigaOS 3.2.2?

[gustavosarmento]

Yep, I'm on Workbench 3.2.2.1. And I don't use any third-party "performance patches" or "eye candy", trying to avoid such strange compatibility issues.

[sacredbanana]

Try the new 1.4.4 release and let me know if it still happens

[gustavosarmento]

Forgot to mention on my last reply that I was already on 1.4.4.

Unfortunately, the issue persists. I'm starting to wonder if it isn't something on my setup, as clean as it may seem...

[sacredbanana]

it weird because it works fine for me (on my MiSTer and in AmiKit)

[gustavosarmento]

Apparently, PeterK on EAB Board found the issue. Says him:

"AmigaGPT seems indeed to have a bug. When reading the stack size from its tool icon it divides the size by 4 by mistake! So, for an entry of 32768 it just sees 8192 bytes of stack.

When I tried 140000 for the stack setting AmigaGPT didn't complain anymore, but 131072 should also work (not tested)."

[gustavosarmento]

Just tested here, and indeed: 131072 of stack size gives no warning. Reducing to 130048 already warns that "a stack size of 32512 bytes is too small".

[sacredbanana]

I added a print statement to read out the stack size. When launching from the tool icon (which is set to 32768) it does indeed have 32768 bytes in stack and also does not show the warning for me. Also tested setting custom stack in CLI when launching from the shell.

[gustavosarmento]

Can I reproduce these steps here on my system?

[gustavosarmento]

Turns out, PeterK went onto great lengths to find that, indeed, the bug is on AmigaGPT's code. Two posts worth noting:

Thanks for your assistance with this issue. I have now fixed it in version 1.4.5
