How D intercepts runtime errors

Thanks for reply, Jarrett. It is exactly what I wondering about.

Yes, I see microsoft c++ compiler has nonstandard keywords to support 
SEH - __try and __except. But i do not have one right now to try it out. 
In mingw/GCC's c++ compiler, on the other hand, there is no support 
(yet, I hope) for it.

Need to say I haven't tried other c++ compilers, but GDC do not support 
it either. And this is really sad.

Is it D language feature, or Digital Mars D compiler? Is such 
functionality part of a language standard or standard library? It would 
be nice if on all compiler implementations one could expect same behavior.
