Windows 7 64-bit: Something triggers Codeblocks to ramp CPU up to 100% (25% on 4 core because CB only uses one core) and closing Codeblocks leaves it running in the background consuming 100% CPU. Not figured out what is causing this yet but it is not compilation because I have been using it as an editor only with three projects in a workspace.

The easiest way is to attach a debugger and break it to see where it is stuck.
Is this reproducible? Does it happen with older night builds? With 17.12?

I noticed the same thing yesterday when I heard my fans spinning louder than they should have been.  Task manager showed codeblocks was the culprit.  I then killed the program in task manager, restarted and the same problem happened again.  After doing that 2 or 3 times, I switched back to the March 10th build and didn't have any problem with the same projects.

I switched back to this build today, but the problem doesn't seem to be happening today for some reason.

Interesting... Let us know if you see it again... If you can find the culprit it would be even better.

Link no idea if it is the same issue https://trac.wxwidgets.org/ticket/17094

Maybe, CodeCompletion plugin may cause the hang issue, but this is only a wild guess. I have to reproduce the issue.  :)
If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.
If they happened together, then turn them to classes.

Full CPU usage is not occuring with 17.12 but continues to occur with SVN 11499. Code completion continues to work whilst in this state. I have not figured out what workflow (if any) triggers this. It looks quite random at the moment. I am running device manager to watch for when this occurs but this is proving challenging to capture.

I started SVN 11499. Opened a workplace with three projects then left it alone. When I came back 30 mins later it was consuming 100% CPU. Then I started SVN 11499 without any projects open and within 5 mins it was consuming 100% CPU. So this is not driven by a manual user workflow. Anyone have instructions on how to gather useful debug info?

Can anyone test disabling and enabling of ThreadSearch plugin?

It crashes on my Win7 64 bit PC.

Edit: I am trying to duplicate the slow down issue and it failed to enable all the plugins.
I plan to build CB from source to see where ThreadSearch crashes; but, it will likely be several days before I can do it.
Edit2: Since ollydbg posted a backtrace I will not try to locate the ThreadSearch location. That is all that I planned to do.
Fixing the reason for crashing is normally beyond my ability.

Normally, I guess the parser goes to an endless loop in this case. I can debug the parser, but I need a test project to reproduce this bug.
Any way, I will review the code changes made recently in the code completion plugin.
Thanks.

Hi, Tim, I just test this. I'm using 32bit mingw-w64's gcc 7.2, and wx 3.1.1 under Windows 7(64bit) OS.
I see that disabling thread-search plugin cause a crash, see the bt below:

Thanks.
For what it's worth, Riban's observation that it seems to happen if you just leave CB idle in the background is an oddly reliable way of recreating the hang (anywhere from 30 minutes to an hour).

A mini procdump of this hung CodeBlocks is available here

And, just for giggles, processhacker shows the offending thread is always stuck in the same place:

I also duplicated the problem no idea how long I let CB idle before seeing it.
I went away and saw the problem after I came back.

I plan on trying the fix suggested in the wx bug post and seeing if it works.
Edit: https://trac.wxwidgets.org/ticket/17094   [wxMSW] High CPU usage when application is idle
Will take several hours since first I have to confirm issue is in wx git master branch
Edit2: Will likely take several days; I will need to test the changes a lot for such a small piece of code.
Edit3: Failed to see problem with CB SVN 11503 and WX Git master less than 5 days old; when only using Core plugins.
Now going to try using core and contrib plugins and see if I can get high CB CPU usage.

That seems to have stopped the problem for me, but I guess I should wait a day or two to say for sure.  What does that plugin do?

Shows the File manager tab next to the Projects tab. It is showing a tree view of the files on the hard disk.
Can someone reproduce this with a build with symbols and show us the function which causes the problem?

Does this happen with the previous night build?
