I am pasting the answer from the question above this one. The long and short, this is a hazard and must be taken seriously.
This site provides a good debate on the issue: http://hvac-talk.com/vbb/archive/index.php/t-82289.html.
The bottom line, though, is that a crack in the heat exchanger of a furnace can be a very dangerous situation. Did the HVAC tech turn the furnace off right away as well? He probably did or at least recommended it.
If you are still unsure call another certified HVAC tech and ask that person. My bet is they say play it safe and that the crack is a real hazard.
To keep legal happy, let me just say that I am not an HVAC contractor, and you should never even look at your furnace without having a qualified, liability accepting HVAC contractor present. To keep sales happy, let me just say that you can find an HVAC contractor that's happy to take your money here: http://www.furnacecompare.com/perl/find_contractors.pl.
