I see no 'Debugger (debug)' tab. I presume you mean the 'Code::Blocks 
Debug' tab, which has lots of stuff on it.

All that the debugger adds (after pressing 'Step-in') is:
[14:38:28.951]: Scanned 0 files for #includes, cache used 0, cache updated 0
[14:38:28.951]: Scanned 0 files for #includes, cache used 0, cache updated 0

Well, this is my attempt at debugging so far:

C:\d\hworld>\dmd\bin\ddbg_gdb.exe bin\Debug\hworld.exe
Ddbg v0.0.5.3 alpha - D Debugger
Copyright (c) 2007 Jascha Wetzel
http://ddbg.mainia.de/

(gdb) break main
Breakpoint 0 at 0x00000000
(gdb) run
Error: couldn't write breakpoint opcode at :0
(gdb) n
Warning: Unknown command 'n' ignored!
(gdb) next
ERROR: Couldn't read from process' memory for disassembly: Only part of 
a ReadProcessMemory or WriteProcessMemory request was completed.

....I haven't used gdb before, but all does not seem to be well!

If I just start and run I get:

C:\d\hworld>\dmd\bin\ddbg_gdb.exe bin\Debug\hworld.exe
Ddbg v0.0.5.3 alpha - D Debugger

LPK.dll  loaded
USP10.dll  loaded
msvcrt.dll  loaded

(gdb)

....which flashes up a DOS box, presumably with the 'hello world' 
output, though it doesn't wait for a key press as it should. If I run 
the program from Code::Blocks (without trying to step) it works ok:

hello world
args.length = 1
args[0] = 'c:\d\hworld\bin\Debug\hworld.exe'

Process returned 0 (0x0)   execution time : 0.015 s
Press any key to continue.


....most odd!
