The 08 October 2018 build (11499) is out.

I'll try to use the 15 August 2018 build for a few days and see if it happens.

@Kilmatead: What happens if you disable the file manager plugin?

As noted by New Pagodi, this seems to have solved it.  At least after giving it a speculative 3-hour "idle test".

Does this happen with the previous night build?

No... I used that build for 2 months with nary a complaint.

Can now duplicate the CPU high usage very fast with nightly build.
With FileManager Enabled, right click on folder and choose refresh under the Management pane and files tab

I am working on building CB using MSys2 GCC with debug build option.

What gdb commands do I need to use/learn to get the information to so someone can fix this bug.

I am a gdb newbie level user; the most advanced command I have used is bt (backtrace).

Edit: Plan is to try the bt (backtrace) command unless someone gives better suggestion.

"thread apply all bt" is better than bt, because it prints the stack for all threads.

I've built several revisions and found that, this starts with rev11463; rev11462 is ok.

Windows 10-x64-v1809
wxWidgets3.1.1-x64 with mingw64-7.2.0

Thanks for doing the bisect. It is obvious that this commit is wrong. I don't know where I've looked while doing the review.

Can you try if this change fixes it:

Yes, this patch fixes the issue. No high cpu when right click-refresh folder, also it's been opened for half an hour.
