GetFlavorType leaking a CFStringRef (16 bytes)

Dear All,

I am seeing a CFStringRef leak when I call GetFlavorType on a drag that I am receiving. The string appears to be a description of the flavorType.

I have sample code (below) that shows the leak quite clearly in when I launch a simple Carbon C++ project using MallocDebug within Xcode. If I comment out the GetFlavorType call then there are no leaks in this code.

I am going to radar this presently, but thought I would ask for comments beforehand in case I have overlooked something fundamental.

Thanks

Douglas

#include <Carbon/Carbon.h>

void DoLeakTest()
	{
	DragRef theDrag = NULL;
	
	FSRef rootFolderRef = {0};
	HFSFlavor hfsFlavor = {0};
	OSType flavorType = '\0\0\0\0';

if ( noErr == NewDrag( &theDrag ) ) { if ( noErr == FSFindFolder( kOnSystemDisk, kVolumeRootFolderType, kDontCreateFolder, &rootFolderRef ) ) { hfsFlavor.fileType = 'fold'; hfsFlavor.fileCreator = 'MACS'; if ( noErr == FSGetCatalogInfo( &rootFolderRef, kFSCatInfoNone, NULL, NULL, &hfsFlavor.fileSpec, NULL ) ) { if ( noErr == AddDragItemFlavor( theDrag, 1, kDragFlavorTypeHFS, &hfsFlavor, sizeof(HFSFlavor), 0 ) ) { GetFlavorType( theDrag, 1, 1, &flavorType ); } } } DisposeDrag( theDrag ); } }

//---------------------------------------------------------------------- ----------------------

int main(int argc, char* argv[])
	{
	DoLeakTest();

    RunApplicationEventLoop();
    return 0;
	}
