TC8ß10-x64:Access violation@closing, while thumbnail extract

[HolgerK]

Access violation @ closing TC, while thumbnail extracting is still active.
(TC8.0ß10 x64, Windows 7 Ultimate x64)

I'm not sure if all conditions are necessary, but here is what did to reproduce the case:

1. Start TC with new ini file where PreloadThumbnails=1 is set
2. Change to Thumbnail View <Ctrl+Shift+F1>
3. Open a huge directory with jpg files in Branch View <Ctlr+B>
4. While thumbnail extraction is still active: close TC

Unfortunately I cannot reproduce it, sorry. I tried it about a dozen times.

Which method do you use for extracting the thumbs?

Which method do you use for extracting the thumbs?

Default:

Maybe the thumbnail cache needs to be cleared before?

The pictures was located on a rather slow network share (MShome).

I did not enable branch view before changing to thumbnail view - but after.

The pictures were jpg's for which I use the Explorer (OLE2) method for retriving thumbnails. I had deleted my thumbnail cache files before testing.

ini-settings:

Code: Select all

[Configuration]
ThumbsLocation=F:\Thumbs
ThumbsCopyDel=1
ThumbOptions=11
ThumbExplTypes=*.*
ThumbPlgTypes=*.thm *.ttf *.fon
ThumbIrfXnTypes=*.*

ThumbWidthNoCache=96
ThumbHeightNoCache=72
PreloadThumbnails=2
ThumbnailPrealloc=100000
ThumbnailMemoryLimit=500

[Colors]
ThumbnailFrame=-1

[ghisler(Author)]

Unfortunately I couldn't reproduce it even with your ini, even after deleting the cache. Could you try again with beta 11, now? I have added some extra checks.

Additional hint:

It seems that the reproducibility is better if TC is maximized and <PgDwn> is used multiple times until you reach an area where the jpgs are not cached.
Closing TC ends here about 80%-90% with an exception.

I can still reproduce the error in TC 8-0b11 x64with an error report that is different in some places:

This time I have also tested with images on the local harddisk - I don't even have to use ctrl+B - all I do is:

1: Switch to thumbnail view
2: Enter a directory with jpg's at about 600-800 kB - there have to be more than can be shown in the file panel at one time.
3. As soon as all the visible thumbnails are generated I close TC (while it is still generating thumbnails that are out of sight) - and I get the Windows error box.

If I close TC while there are still visible files for which thumbnails are NOT yet generated i do NOT get the error.

I happens when I close TC with the red X in the top right corner OR with TC's "Alt+F4 Exit" button - but not if I use Alt+F4 keypress to close TC.

I can add that I cannot reproduce the error in the 32bit version of TC.

[ghisler(Author)]

I'm sorry, I cannot reproduce it. What's strange is that the error occurs outside of my code, so TC's crash report function doesn't catch it.

tcunzl64.dll_unloaded seems to indicate that it occurs when the tcunzl64.dll is being unloaded, but that doesn't make any sense.

It seems that it only happens if PreloadThumbnails is set to 1 or 2 - apart from that I can reproduce it with a fresh ini file.

Ah, I see - I will try that, thanks for the hint.

[petermad]

Seems to be fixed in TC 8.0b12 x64

[ghisler(Author)]

Thanks, can anyone confirm it please?

[HolgerK]

Sorry for the late reply (Little time for testing these days, I'm currently moving to a new domicile).

I could reproduce the bug with TC8.0ß11 x64 on a different windows 7 machine but no more with TC8.0ß12 x64.
So it seems to be fixed.

Thanks
Holger
