memLeak at ArcGISTiledLayer and Basemap

NorbertThoden

Hi!

Does ESRI know that there is a memory Leak using

ESRI::ArcGISTiledLayer, ESRI::Basemap (V100.5 and V100.6))

Creating and destroing a simple map WITHOUT terminating the application.

Valgrind (@V100.5)

and some more

I am already in contact with the support team, but no real progress ...

Hi Norbert,

I'm having trouble with that download link that you supplied but I believe I can reproduce the same thing with my own code. We will try and look into that and also any information that comes through via the support issue you logged.

Here's a snippet of the repro code I'm using - let me know if that looks substantially different to what you are doing:

void TestMemoryLeakQuick::recreateMap()

{

  emit usedMemoryBytesChanged();

  qDebug() << usedMemoryBytes();

  if (m_parent)

  {

    delete m_parent;

    m_parent = nullptr;

    m_mapView->setMap(nullptr);

    m_map = nullptr;

  }

  m_parent = new QObject(this);

  const QString tpkPath{".../tpk/SanFrancisco.tpk"};

  auto tileCache = new TileCache(tpkPath, m_parent);

  auto tiledLayer = new ArcGISTiledLayer(tileCache, m_parent);

  auto basemap = new Basemap(tiledLayer, m_parent);

  m_map = new Map(basemap, m_parent);

  if (m_mapView)

  {

    m_mapView->setMap(m_map);

  }

}
