My Eclipse keeps resetting the project settings for the C++ preprocessor includes providers, specifically the Build Output Parser and the Built-in Compiler. I've tried recreating the project, but it doesn't help. The project is of type "Makefile project with existing code". I'm not doing anything special to trigger it - just writing some code.
It seems to happen more often when I do git operations, but the .cproject, .project, and .settings files/folders are not in source control - they are in my gitignore filter file and not added. See the following.
$ git ls-files -o -i --exclude-standard | grep -e project -e settings
.cproject
.project
.settings/language.settings.xml
It varies a lot how often it happens. Sometimes it's 5-10 minutes between resets, sometimes it's hours.
Stat output is a bit interesting, after Eclipse has started reindexing with the new settings. As the read date has not been updated, does it mean that the file has only been written and never read, i.e. Eclipse must have been the one updating it?

Has anyone had similar problems? Is there some way to troubleshoot Eclipse, seeing what it thinks happens? Its .log file is not written to when the problem occurs.
