I forgot to mention how to call the program to show the bug. This is
done as follows:

     ./a.out 200 20
     BUG: 00000000000000000061 appears twice!
     stat() error (testbugdir/input/00000000000000000061) : No such file or directory
     BUG: 00000000000000000061 appears twice!
     unlink() error (testbugdir/output/00000000000000000061) : No such file or directory

or:

     ./a.out 50 61
     BUG: 0000000000000000000000000000000000000000000000000000000000020 appears twice!
