   The problem was triggered when I was debugging something   
   completely unrelated in the OS with a printf. I tried removing   
   that printf and DI is now set to something sensible and it is   
   working.   
      
   I'll see if I can figure out what's happening.   
      
   There was a file open done, so maybe DI is not being   
   preserved over that.
