May this be a bug in `sprintf'? Or is it just a coincidence that it trys 
to access 99 bytes when the format is "%.99s"?

The debugger itself prints the string with only 48 bytes:

  strlen("lwrite("This is a test"); I wonder where we are") == 47

The block size seems to be OK: 20 bytes of header (5 integers/pointers) +
48 bytes for the string == 68 bytes.
