never used Memory storage that way, but I've used this for ages

	storageObj = ::Q3MemoryStorage_New(NULL,0);
	::Q3File_SetStorage(fileObj, storageObj);
	::Q3File_OpenWrite( fileObj, fileMode );
	::Q3View_StartWriting(dummyView, fileObj);
	::Q3DisplayGroup_Submit(groupObj, dummyView);
	::Q3View_EndWriting(dummyView);
	::Q3File_Close(fileObj);
	::Q3MemoryStorage_GetBuffer(storageObj, &buffer, &size, &count);

	metafile = operator new(size);
	memcpy(metafile,buffer,size);

so probably QD3D has a lazy allocation, try using the Q3RawData_Write 
procedure to allocate the buffer and then get it

or just allocate the buffer and pass it to Q3MemoryStorage_New
