I beg to differ.

#include <stdio.h>

int main()
{
   char *str = "test\nbar\n";
   char c;
   FILE *stream;

   stream = fmemopen(str, strlen(str), "r");
   while (EOF != (c = fgetc(stream)) && !ferror (stream)) {
      putchar (c);
   }
   if (ferror (stream))
           fprintf (stderr, "ferror!\n");
   if (feof (stream))
           fprintf (stderr, "feof!\n");
   fclose(stream);
   return 0;
}

results in:
test
bar
ferror!

Hm. When the \n after bar is omitted, the ferror gets thrown right after
reading and writing the line "test". Now, I also believe that this is a
bug.

Eray, I owe you an apology.
