Preprocessor bugić u Visual C++ 8.0 kompajleru, ili sam ja slep

^{02.09.2006. u 02:52 - pre 214 meseci}

Može li još neko probati da iskompajlira ovo parče koda u Visual C++ 8.0, kod mene se ne kompajlira :)

Code:

#include <new.h>

//hackfix:
//template<class T> void * internal_alloc( int locationID, int lineNumber, const char * pFileName, const char * pCompilerBugFix = 0 )
template<class T> void * internal_alloc( int locationID, int lineNumber, const char * pFileName )
{
return 0;//malloc( sizeof(T) );
}

//hackfix:
//#define internal_new( __obj_type, ... ) new( internal_alloc<__obj_type>( __COUNTER__, __LINE__, __FILE__, "" ) ) __obj_type( __VA_ARGS__ )
#define internal_new( __obj_type, ... ) new( (internal_alloc<__obj_type>(__COUNTER__, __LINE__, __FILE__)) ) __obj_type( __VA_ARGS__ )

void main()
{
int * pTest1 = internal_new( int ); // this one doesn't work properly
int * pTest2 = internal_new( int, 1 ); // this one works properly

// preprocessed output, buggy version:
//int * pTest1 = new( (internal_alloc<int>(0, 16 ".\\blahblah.cpp")) ) int( ); <- notice the missing comma after '16'
//int * pTest2 = new( (internal_alloc<int>(1, 17, ".\\blahblah.cpp")) ) int( 1 );

// preprocessed output, hackfix:
//int * pTest1 = new( internal_alloc<int>( 0, 16, ".\\blahblah.cpp" "" ) ) int( );
//int * pTest2 = new( internal_alloc<int>( 1, 17, ".\\blahblah.cpp", "" ) ) int( 1 );
}

Bug je u preprocesoru, skida pogresan zarez za slucaj kad __VA_ARGS__ nema argumente!
