Right off the top of my pointed little head:

Have you looked at the .err file (if it exists)? That might point you in a direction, maybe even the right one.

However, the fact that you can copy everything to a new computer and it compiles just fine makes me lean towards the idea that you might have a sector trying to go bad and one of your files is sitting on it. Especially when you try to create a new project with the same files. To test this, my suggest would be to copy off the files, delete them completely and run some diagnostics on your drive. I would suggest a de-frag, but that would probably only put another file on the 'bad' spot and move your problem around.

After a re-boot, copy your files back out and try rebuilding/recompiling.

The problem appears both when compiling an EXE, and when rebuilding the project, whether I select "recompile all files", or not.

When creating a new project (of course, I suspected project corruption), and include the same main program, the error also appears.

All files in the project directory and subdirectories have attributes "A" or "" (IOW, no read-only files).

We have no problems creating or modifying files in the directory.

Several GB of free disk space.

If we copy the entire project to another computer, it works.

Compiling other projects on the same computer, also works.
