That linker error can only happen if the symbol _DEBUG is defined.
Otherwise, the header file crtdbh.h will define _malloc_dbg to the
normal malloc() API.
The question is now where that _DEBUG got defined.
Please check the following:
* remove the folder \ext\apr\release_win32 and ext\apr\debug_win32
manually. Maybe the 'clean' task didn't work correctly.
* make sure you use a new DOS shell before calling the Nant script again
* also make sure you call %VS80COMNTOOLS%\vsvars32.bat, and not another
script (e.g. the one from VS.NET2003).
* check the paths in VS2005->Tools->Options->Projects and
Solutions->VC++ Directories. Especially the include dirs. Make sure you
don't have anything in there before the VS2005 directories if you're not
absolutely sure that the files in those paths are ok.
