any hints? Is it an error and if so has it been fixed?

The error is in your program.  To wit:

           status = ftruncate(fd, 6);

You *must* either have a prototype for ftruncate in scope, or explicitly
cast the argument to `off_t'.  The problem is that what you're passing
to ftruncate() is an int, and it tries to read an off_t and gets 32 bits
of garbage.
