System.Drawing.Common 'Out of memory.'

Question

When I execute the following code snippet in a Linux environment, an out of memory error occurs.

System.Collections.Stack GraphicsStateStack = new System.Collections.Stack();
Bitmap bmp = new Bitmap(500,600);
Graphics gm = Graphics.FromImage(bmp);
for(int i=0; i<1000; ++i)
{
GraphicsStateStack.Push(gm.Save());
GraphicsState st = (GraphicsState)GraphicsStateStack.Pop();
gm.Restore(st);
st = null;
}

But I did not find that the memory is being used a lot.

My environment information is as follows:

The same code does not report an error under window.
This confuses me.

Answer 1

This problem seems to be resolved in libggdiplus6.0.5.
The library I compiled with the latest code does not have this problem.
