This testcase segfaults with the Red Hat glibc-2.2.4-19.3 rpm.  AFAICT, the

No.  If a file descriptor is closed it no file descriptor anymore.
The runtime library is not there to catch the programmers bugs.



Oh, I love this argument. :-)

We should bzero the contents of FILE* on fclose, and return lovely documented error if told to fclose FILE* again. Why? Because API does not document segfault behavior :-)
