>Description:

fclose(NULL) produces a segmentation fault error.

Perhaps it should return EOF and set errno to EBADF.

Then again perhaps the users deserve what they get for handing
random junk to libc functions.

>How-To-Repeat:

Compile and run the following program:

#include <stddef.h>
#include <stdlib.h>
#include <stdio.h>
#include <assert.h>

int
main(int argc, char *argv[])
{
  int ret;
  ret = fclose(NULL);
  assert(ret == EOF);
  perror("fclose");
  return(EXIT_SUCCESS);
}
