This problem exists in 7 typeinfo files and every time in getHash 
function. All other files compiles fine.
I can live without these now. When is getHash called? By compiler 
or by user?


What does option -fno-rtti exactly do and what D features are not 
available? I noticed this with -fno-rtti:
int * i = new int;  // <-- compiler error
myclass c = new myclass(); // <-- passes, dies at runtime


There were big changes in exception handling code about 2 years 
ago and my exception code stopped to work. What was changed back 
then? How can I get my code to work again? Could this be some 
struct alignment problem like some years ago?
