Hi Skysider,

  Thanks for reporting this problem.  As Andreas explained the current code
will handle the corrupt input file correctly, but I also accept your point that
it will use up a lot of CPU resources whilst doing so.  So I have checked in a
small patch which causes the read_formatted_entries() function to fail before
starting the loop, if it knows that the loop cannot possibly terminate
successfully.

Cheers
  Nick
