This means that the preprocessor failed unexpectedly.

Is gcc perhaps a wrapper or a masquerading symlink (what does "which gcc" say?)?

One way of troubleshooting the problem is to locate "Result:
preprocessor error" in testdir.XXXXX/ccache.log, then look for the
previous "Running preprocessor" log. After that log line, it says
"Executing /path/to/gcc ...arguments...". That's the command that
failed. Try running it manually to get some clues.
