1. You can use environment variable to enforce desirable behavior
   all the time without your involvement.

2. In debugger (when it matters IMO) the break point is triggered 
   regardless. If it's not the case it might be an issue.

3. I personally believe this is better way to report this error 
   condition then test module is executed from command line. If 
   I need to run in debugger I can always do this.

4. There is command line argument (auto_start_dbg) which should 
   attach debugger automatically at the point of failure (instead 
   of reporting error and aborting test module). It does not works 
   for all debuggers yet, but it works very well on NT.
