I hope that in all the non-void cases ferror() is called after printing, 
but my guess is that it isn't.

For instance, I had problems with pkg_create(1), which doesn't check the 
list of file names passed to the tar(1) child process. It just dies 
without printing an error message. That makes detecting faults really 
difficult.
