Note: that "a.out" binary is modified from  your original code.

It's modified to correctly print out the readdir() results, but it's
also modified to open just "ptmx" for the above trial (so it doesn't
open /dev/ptmx, it's opening that ptmx node in the current directory,
which is why it then reports that

   I point to "/home/torvalds/dummy/pts/0"

thing.

So it's not your *original* test-program, it's slightly tweaked for this test.
