#417 Drag/Double Click Crash on Queues

Latest Subversion
Interface (116)

Start game up, enqueue the rightmost tech on the queue by double-clicking. Start double clicking furiously on the top of the tech queue, while dragging the mouse around. Eventually while doing this, I get a crash. The app freezes with a tech panel being dragged and the mouse over top. The cursor is usually over the panel that was dragged off the queue, and I think this occurs when I click again on the being dragged and dragged away panels.

The debugger catches a crash, and the error is:

Unhandled exception at 0x10154a63 (GiGi.dll) in freeorion.exe: 0xC0000005: Access violation reading location 0x00000128.

The location in code is:

> GiGi.dll!GG::ListBox::Row::operator[](unsigned int n=0) Line 239 + 0x3 bytes C++
freeorion.exe!QueueListBox::Render() Line 45 C++

which is:

Control* ListBox::Row::operator[](std::size_t n) const
{ return m_cells[n]; }

Perhaps rendering is happening part way through the listbox row delete operation?

    Fixed in GG Subversion. (The fix wasn't in the FreeOrion code
    itself, but in GG, the GUI library FreeOrion uses.)
