TC 8.0 x64 compare by content crash

[LoRenZoR]

Hi,

I have just stumbled upon the following issue:

If I use the compare by content option with the 64bit client and use find with backward search (SHIFT+F3), I get wierd pop-up message (not all the time but I can still hear the assigned sound in the OS) and after pressing SHIFT+F3 2 or 3 times more, the program gets terminated.
I also saw wierd directory listing in the background when I triggered this error. I was able to reproduce this whenever I tried to search backwards.

I made some screenshots, please check them out as well:

Backgrond (note that you should see the same content in both panels)

My OS is Windows 7 x64 with SP1. I could neither reproduce this with the 32bit client, nor on Windows XP x64.
I hope this will not be a duplicate post because I have checked the latest topics and search for this and well but could not find this mentioned.

Confirmed in TC x64 (TC x32 is not affected), and it's very strange.
Steps to reproduce:
1. Create any text file
2. Compare that text file in TC x64 with something else in its directory
3. Use Shift+F3 to search for some existing text - the first occurrence should be selected
4. Use it again

Now you may see that weird dialog, you may hear a "ding" sound (a different that usual), plus the dialog may contain a warning icon just before the "R" char. Whether you see it or not seems to be random.

But what is more interesting is, that when this happens, TC creates a file called "C" in the directory containing both compared files. And this file contains a small section of TC's wincmd.ini - more precisely parts related to file comparison.

Cannot reproduce. I get the following dialog (with English language):

---------------------------
Not found:
---------------------------
a
---------------------------
OK
---------------------------

Can you send me two files and the search string to use to get this error, please?

Here is a video (sorry about the compression, something is wrong with my encoder):

Note: in 00:09 and 00:16 I pressed Shift+F3.
Also, it looks like the creation of file "C" and its contents is also random, not just the error dialogs.

ghisler, try again by searching a string of at least 2 characters.
This is definitely reproducible. Stop at the first occurence of the string, then press shift+f3. Use a file that only contains the word test and another empty file. Compare them, then search for "te", then shift+f3.

If the debugger is attached to the process, this is what it bumps into:

If I continue the execution of the process, memory corruption occurs.

I can confirm the bug in TC 8.0 x 64 with two files like umbra's:

One file with the content:

Code: Select all

123
456

and one blank file.

1. I open the two files in CbC
2. I press Shift+F3, write 123 and press Enter.
3. I close CbC dialog and open it agin.
4. I press Shift+F3 (123 is now prefilled) and press Enter.
5. I press Shift+F3 and get a soft ding.
6. If I press Shift+F3 again I get the almost empty error box just with an L (not an R as umbra does).
7. After that TC gets unstable and hangs and eventually craches.

If I skip step 3, I don't get the errorbox, but after a few Shift+F3 presses TC hangs.

I can also confirm that a file C with some wincmd.ini content is written in the same directory of the two test files.

If I test with a clean wincmd.ini I have so far obtained different Windows reports when crashing:

I have also had a file named F written with something that looked like the [MRUD] section of imagine.ini - that was when testing with my normal wincmd.ini file - hence with plugins enabled.

Thanks, I can reproduce it with your files. It really depends on what files you search in...

[umbra]

In TC 8.01 rc1 it doesn't crash anymore.

[petermad]

I can confirm that TC 8.01 RC1 x 64 no longer crashes

Thanks!
