EXC_BAD_ACCESS when closing app in iOS

[thinium]

Hi! For some reason my app is crashing when closing the app on an iPad.

It first crashes in ImGui::Shutdown() inside SaveSettings().

Since I don't care about saving settings I comment out SaveSettings() and then it crashes in the following for loop:

for (int i = 0; i < g.Windows.Size; i++)
    {
        g.Windows[i]->~ImGuiWindow(); // <-- crash here
        ImGui::MemFree(g.Windows[i]);
    }
...
ImGuiWindow::~ImGuiWindow()
{
    DrawList->~ImDrawList(); // <-- crash here
    ImGui::MemFree(DrawList);
    DrawList = NULL;
    ImGui::MemFree(Name);
    Name = NULL;
}

Shutdown is called automatically before exit callbacks because it's in some kind of "release pool".

Do you have any ideas for debugging this? The same program was working fine last year, but I don't know if an update to OF (now 0.10), to my program or to iOS is causing this. ofxImGui has not been changed in my system.

I would try

if(DrawList)
{
  DrawList->~ImDrawList();
  ImGui::Memfree(Drawlist);
}

Thanks for the suggestion! It turns out that our imgui object is not explicitly deleted during destruction phase. Now it's working fine :)
