import std.stdio;

unittest
{
     try {
         writeln("throwing");
         throw new Exception("unfortunate");

     } catch (Exception exc) {
     }

     writeln("life goes on");
}

void main()
{}

Note that some exceptions are not descendents of Exception:

     Throwable
      /     \
  Error    Exception

If you really have to, you can catch by Error or Throwable. However, 
catching by Error or Throwable is not advisable because you can't be 
sure of the state of the program when such an exception is thrown.

Unfortunately, segmentation faults are not translated to exceptions.

P.S. This thread would be interesting to people who follow the D.learn
