In the past, I'd tried some of the debuggers with D and had bad experience
with them. I just gave ddbg another try and it is now quite useful.

Test file: test.d

 class Foo
 { int xx; } 
 
 void main()
 {
   Foo f;
 
   f.xx = 1;
   bool assign = false;
   int x;
   assert(assign);
   {x = 1;}
 }


I compiled with "dmd test.d -g" the fired up ddbg with "ddbg test.exe".

I used the "r" command and it ran the program and halted at the Access
Exception...

C:\temp>ddbg test.exe
Ddbg 0.08.1 beta - D Debugger

Which is exactly what I hoped it would show. So maybe now I can live
without compiler code checking for access violations.


THANKS JASCHA.
