A clean all will resolve this and things will behave again.

This is happening several times a day with incremental builds, and had been intermittently troubling me for some time now, without me actually knowing what was going on.

I would do a clean build and record the build commands, then do an incremental build and compare the build commands for the relevant translation units (the one where the class is implemented and the one where it's being used). Do the build commands differ between the clean and incremental builds?


Second, if this involves header files and preprocessing, I suspect problems with precompiled headers. You could try disabling their use to see if that makes the problem go away.

Regards,
Ken
