Crash with CustomWidget

[SpiderPig]

I've only had this happen when using a custom widget.  If you hide the parent of the custom widget before at least one loop it will crash.

#include "Engine.h"

using namespace UltraEngine;

//Declare new style constants
enum CustomWidgetStyle
{
    CUSTOMWIDGET_DEFAULT = 0
};

//Declare new widget class
class CustomWidget : public Widget
{
    bool hover;

protected:

    virtual bool Initialize(const WString& text, const int x, const int y, const int width, const int height, shared_ptr<Widget> parent, const int style)
    {
        return Widget::Initialize(text, x, y, width, height, parent, style);
    }

    //Called when the mouse moves if this widget has the focus
    virtual void MouseMove(const int x, const int y) {}

    //Called when the mouse cursor enters the widget bounds
    virtual void MouseEnter(const int x, const int y)
    {
        hover = true;
        Redraw();
    }

    //Called when the mouse cursor leaves the widget bounds
    virtual void MouseLeave(const int x, const int y)
    {
        hover = false;
        Redraw();
    }

    //Called when the mouse button is pressed
    virtual void MouseDown(const MouseButton button, const int x, const int y)
    {
        if (button == MOUSE_LEFT) EmitEvent(EVENT_WIDGETACTION, Self());
    }

    //Called when the mouse button is released
    virtual void MouseUp(const MouseButton button, const int x, const int y) {}

    //Called when another widget becomes selected
    virtual void LoseFocus() {}

    //Called when mouse double-click occurs
    virtual void DoubleClick(const MouseButton button, const int x, const int y) {}

    //Called when mouse triple-click occurs
    virtual void TripleClick(const MouseButton button, const int x, const int y) {}

    //Called when widget is selected
    virtual void GainFocus() {}

    //Called when key is pressed
    virtual void KeyDown(const KeyCode key) {}

    //Called when key is released
    virtual void KeyUp(const KeyCode key) {}

    //Called for each keydown event
    virtual void KeyChar(const int keychar) {}

    //Called when mouse wheel turns and mouse is hovered over this widget
    virtual void MouseWheel(const int delta, const int x, const int y) {}

    //Called each time the widget is redrawn
    virtual void Draw(const int x, const int y, const int width, const int height)
    {
        blocks.clear();

        AddBlock("Text", iVec2(0), this->size, Vec4(1), TEXT_CENTER | TEXT_MIDDLE);
    }
public:

    //Constructor
    CustomWidget() : hover(false)
    {}

    friend shared_ptr<Widget> CreateCustomWidget(const WString&, const int, const int, const int, const int, shared_ptr<Widget>, const CustomWidgetStyle);
};

//Create function
shared_ptr<Widget> CreateCustomWidget(const WString& text, const int x, const int y, const int width, const int height, shared_ptr<Widget> parent, const CustomWidgetStyle style)
{
    auto widget = std::make_shared<CustomWidget>();
    widget->Initialize(text, x, y, width, height, parent, style);
    return widget;
}

int main(int argc, const char* argv[])
{
    auto displays = GetDisplays();
    auto window = CreateWindow("Ultra Engine", 0, 0, 800, 600, displays[0]);
    auto framebuffer = CreateFramebuffer(window);
    auto world = CreateWorld();

    auto camera = CreateCamera(world);
    camera->Move(0, 0, -3);
    camera->SetClearColor(1, 0, 0);

    auto box = CreateBox(world);

    auto default_font = LoadFont("Fonts\\arial.ttf");
    auto ui = CreateInterface(world, default_font, framebuffer->size);
    ui->SetRenderLayers(2);
    ui->root->SetColor(0.0f, 0.0f, 0.0f, 0.0f);

    auto ui_camera = CreateCamera(world, PROJECTION_ORTHOGRAPHIC);
    ui_camera->SetPosition((float)framebuffer->size.x * 0.5f, (float)framebuffer->size.y * 0.5f, 0);
    ui_camera->SetRenderLayers(2);
    ui_camera->SetClearMode(CLEAR_DEPTH);

    //Create widget
    auto panel = CreatePanel(10, 10, 100, 100, ui->root);
    auto widget = CreateCustomWidget("Custom", 20, 20, 50, 30, panel, CUSTOMWIDGET_DEFAULT);

    while (true)
    {
        panel->SetHidden(true);//Causes crash
        while (PeekEvent()) {
            auto ev = WaitEvent();
            ui->ProcessEvent(ev);
        }
       // panel->SetHidden(true);//No crash here

        world->Update();
        world->Render(framebuffer);
    }
    return 0;
}

The fix for this is available in the new 1.0.2 channel.
