Don't crash when the file has a self cycle.

When there's a self cycle, the compiler.log gives an (out-of-spec) error of the form:
```
FAILED: Tst has a self cycle
```

Notice the compiler is silent when the cycle involves more than one file (the terminal shows an error, but compiler.log is empty).
