From the official Downloads page, via the SourceForge link. By now I've also downloaded it from the dAppCDN link -- apparently, the two installers are not byte-identical (with the SourceForge installer reported as 52,312,337 bytes; dApp installer 52,313,001 bytes).

If it helps, this is also the information reported under "Help > About" :

Disabling all plugins (temporarily) was my choice here.

--- Quote ---Please start CodeBlocks with the '/d' parameter to create the debug log.

After the windows disappears please show us the data written to the CodeBlocks log.
Click on the "CodeBlocks" log tab, place the mouse in the log window and scroll upward to see the data.
Right-click and choose "copy contents to clipboard".
Paste that data to use between code tags (The # icon above a reply box).

Do the same with the "Code::Blocks debug" tab and window.

We'd like to see what is being logged when you save a file.

Thanks for your reporting and patience.

On it.

...maybe I should have chosen a smaller project than GIMP to demonstrate with, but regardless, upon saving a file this appears in the Codeblocks main log:

--- Code: ---wxDir::GetAllFiles 0.824000 s
makePathsRelativeIfNeeded 0.807000 s
filterOnWildcards 0.318000 s
Loading directories took 2.034000 s
Adding took 10.537000 s
Loading globs took: 12.699000 s
ProjectManagerUI::RebuildTree took 0.577 seconds
Rebuilding tree took: 0.578000 s
--- End code ---

Nothing at all appears in the Debug log when saving.

Ten seconds is a noticeable wait, but the editor window is still open prior to that.

And this is the full log (open project, open a file, dummy edit, save file):

Where can I download the source causing the problem.
I want to re-create the problem while running CB under the debugger.

Also, are you sure that the Code Completion plugin is disabled?
That wait after saving feels like a timer pop then running some code.
Or a lock on the main gui code being released.
Very suspicious of a bug from last century.

Like I said, from the Sourceforge.net page linked from the Codeblocks Downloads page:
1 - https://www.codeblocks.org/downloads/binaries/#imagesoswindows48pnglogo-microsoft-windows
2 - links to -> https://sourceforge.net/projects/codeblocks/files/Binaries/25.03/Windows/codeblocks-25.03-setup.exe

For certainty, the SHA1 hash of the installer should be 99eafbb34f62cfaee58da6e0ae6e0b4ce88c9f1e (I downloaded a fresh copy from SF and it matches), though this does not match ANY of the signatures cited by the dappCDN downloads page (https://dappcdn.com/download/devtools/code-blocks?get=codeblocks-25.03-setup.exe).

If I download the equivalent installer from dappCDN, its SHA1 hash is accd7900ec89ec9bf1f45bc70dfd20dbb4a350f6 and this does match the signature cited on the page. I will try installing that one separately for comparison. (And in any case, the SHA1 of the main executable, codeblocks.exe, is the same either way: 7d16aadf9e10ab7fa39decedc6714bfcee5623f1)

And that is correct: I have ALL plug-ins disabled.

I would love to load one of GIMP's dependencies (like babl) just to have a second (smaller!) project as a datapoint, but for the moment I cannot actually create any new projects (no templates available), nor can I simply point CB at the source folder either.

Additionally, this all does not occur if I simply open a file directly (outside any project) and make/save changes. There is no strange lag after saving, the editor window stays open (as it should). And it is consistent between both installations.

In other words, this seems SPECIFICALLY correlated to the overall size of the project (as shown above in the logs: 3653 code files requiring 56.614 seconds to load).

Pecan:
@Statelier

I was asking about where to download the Gimp source that's shown in the project window.

But I finally found it (I think). Downloaded it, made a project from it, and tried to get the problem as described. No luck though. It works ok for me. (Windows 11 64bit 32Meg memory).

Now I'll re-create cb 25.03 from source and see if I can step through "save" in the debugger with many files of Gimp loaded.

Please describe the hardware you're using. I'd like to use vmware to create a similar system and test your environment there.

Stratelier:
Sorry. At the time I was following the instructions from developer.gimp.org (and there are quite a few more for Windows than on Linux), one of which is to fetch it via git command-line.

The issue does seem specifically related to very large projects, as I cannot reproduce it in isolated files or "hello world" sized projects.

As for my system: A laptop from 2014 with 4GB shared RAM. It has room for 8 to 16GB but the RAM sockets are the last thing in the teardown (ugh). So it tends to be under a bit of stress.
