I tried your example duplicating your error. I played with it and change it
little bit to get it to work. Instead of using printf() in your T1_dl.c I used
cout and compiled it with g++ instead of gcc. Could it be you mixed C++ streams
used in your T1 class with old C printf-family what brings your application in
knee? I won't be surprised, I read somewhere that this two concepts should not
be mixed.
