Add a single binding size_t headerSize = header->payloadSize() above the if &
use it throughout?

         info.liveCount[gcInfoIndex]++;
-        info.liveSize[gcInfoIndex] += header->size();
+        info.liveSize[gcInfoIndex] += header->payloadSize();
     } else {
         deadCount = 1;
         deadSize += header->payloadSize();
         info.deadCount[gcInfoIndex]++;
-        info.deadSize[gcInfoIndex] += header->size();
+        info.deadSize[gcInfoIndex] += header->payloadSize();
     }
 
     pageDump->addScalar("live_count", "objects", liveCount);
