Hello! Thanks for submitting an Issue :D

Which Version of Mnemosyne are you using? Have you tried to use the new Version 1.1.0?

Also can you let me know what OS version you are using?

bubbob42 · 2023-10-30T20:58:41Z

Hi! I used 1.0.2 from AMinet. Will retry with a newer one, thanks! :)

OS: AmigaOS3.2.2.1

bubbob42 · 2023-10-30T21:04:05Z

Checked with 1.1.0 - same issue here. It's even a bit worse, because now the "Scan" button causes the breach as well - it did not in 1.0.2

Arisamiga · 2023-10-30T21:42:42Z

Checked with 1.1.0 - same issue here. It's even a bit worse, because now the "Scan" button causes the breach as well - it did not in 1.0.2

Hello again @bubbob42 I tried to reproduce the error using the attributes you had but I wasn't able to.

Can you please let me know:

If you are using any distribution or any patches on your machine.
The steps you took to reproduce the error.
Have you tried to fully restarting your machine to see if you still get the error?

bubbob42 · 2023-10-31T06:10:50Z

If you are using any distribution or any patches on your machine.

No, see attached syslog and machine/software report.
A4kT.txt
syslog.txt

The steps you took to reproduce the error.

Boot, start Mnemosys from Workbench. Select drive, hit scan (breach), doubleclick subdirs (breach), hit back button (breach).

Have you tried to fully restarting your machine to see if you still get the error?

Yes.

bubbob42 · 2023-10-31T07:35:59Z

I tested again using another machine (A1200) with both OS3.2.2.1 and OS3.3 alpha. No problems here!

Will do some research why it produces hits on my A4000T.

Arisamiga · 2023-10-31T07:38:49Z

I tested again using another machine (A1200) with both OS3.2.2.1 and OS3.3 alpha. No problems here!

Will do some research why it produces hits on my A4000T.

Yea. I suspect it might be because of the processor but not sure. I will try to create your setup on an emulator and see if I get the same issue. If you find any other information let me know :D

bubbob42 · 2023-10-31T08:08:08Z

Will do. Both machines are 060s, only different Revs.

bubbob42 · 2023-11-01T15:26:48Z

Successfully reproduced the bug with two other machines (A2000 and A4000). It can also be triggered when the machines are booted into FailSafe mode.

WipeOut log (when hitting "Scan" button):

mnemo_wipe.txt

Other users can reproduce the bug as well. I'd suspect the chunks being allocated during recursive routine have to be a bit larger (but I didn't check the code, so just guessing here).

Successfully reproduced the bug with two other machines (A2000 and A4000). It can also be triggered when the machines are booted into FailSafe mode.

WipeOut log (when hitting "Scan" button):

mnemo_wipe.txt

Alright Great! I tried it with WipeOut as well and I am able to recreate it. Gonna see what this is happening

Alright, I think I might have figured this out.

@bubbob42 is there any chance you can check if this version creates the problem: Mnemosyne-1.1.0-dev.zip

Hi Aris,

will try ASAP.

The dev-version fixes the issue for me - very nice!
