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]

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

OS: AmigaOS3.2.2.1

[bubbob42]

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]

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]

• 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]

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]

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

[bubbob42]

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).

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

[Arisamiga]

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

[bubbob42]

Hi Aris,

will try ASAP.

[bubbob42]

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