Thank you for helping. I did what you suggested and started commenting 
out code to get it working. I finally got to a working code with just 
two lines commented out:

http://github.com/ivans/ifs3D/commit/339ca5ee58661d636bfcd878c08b06bacede7dca

These lines have nothing to do with streams and stdout, so I still don't 
understand what is going on. But this part of code is very old and 
stupid (allocating a lot of unneccessary real[][]'s) so I guess the next 
step is to figure out a smarter way to do that part and see if the 
exception goes away :).

Uh I have missed debuging D programs :).
