Which isn't really equivalent to DMD for most C++ compilers, where 
specifying debug symbols also sets a special define (where as D's -debug 
and -g are two different things). Some C++ compilers also handle 
variable initialization differently when debug mode is turned on, which 
is one reason why some bugs are more likely to show up in release mode. 
All D's debug mode does is make version(debug) true.
