Thanks to Sergei, again, and a lot of single-stepping through the 
StreamBuffer initialization, I found the problem. malloc couldn't
allocate space for the io_bufs of stdin and stdout.

That was caused by a wrong calculation for the heap-size in the
memory-layout definition. I fixed that and printf is working fine now.

Cheers and thanks to Sergei!
