title: error when run hprof-conv.exe
body: <p>I got error <code>ERROR: read 46402 of 4259932 bytes</code> when run <code>hprof-conv.exe</code> and the file it created could not be opened with MemoryAnalyzer.exe with error <code>Illegal record length 0 at byte 5,408,931 for record type 1</code>.</p>
  
  <p>I used <code>android.os.Debug.dumpHprofData("/data/misc/dump.hprof");</code> to created the dump file and used <code>C:\&gt;adb pull /data/misc/dump.hprof</code> to get the dump file from emulator.</p>
  
  <p>Does anyone know what's wrong here? It used to work the first couple times after I reboot my computer.</p>
