----------------
This comment is confusing for me. Maybe there are typos here?
Isn't the 'freopen' failed? `fopen` was successful and it's return value was
checked in line 153.
`f1` seems to be ok here (still associated with "foo.c"), only `f2` is bad, as
we see in line 162.
Or `f1` is already closed here, even though it could not open the new file?
