Hi!

I am new in D language. I implement a little 2D/3D engine, and during the development I faced an interesting problem.

I have this function:

 void addBackgroundToLayer2(char[] textureName, float posx, float posy)
    {
        CTexture tex = new CTexture(textureName); //create the texture

        tex.m_itexurePosX = posx;
        tex.m_itexurePosY = posy;
       writefln("X: %f, Y: %f", tex.m_itexurePosX,tex.m_itexurePosY);

        m_Layer2~=tex;
    }

The problem is that the value of tex.m_itexurePosX variable will be "-nan". But value of posx is good.

If I change the sort of the lines:

 void addBackgroundToLayer2(char[] textureName, float posx, float posy)
    {
        CTexture tex = new CTexture(textureName);

        m_Layer2~=tex;

        tex.m_itexurePosX = posx;
        tex.m_itexurePosY = posy;
       writefln("X: %f, Y: %f", tex.m_itexurePosX,tex.m_itexurePosY);
    }

Then everything works fine. What do I wrong? I do not understand this problem. I use dmd 1.037 compiler.

Looks like a bug. Could you please provide a compilable code sample (small one, 
if possible) so that we could reproduce it?

BTW, you have a typo in 'm_itexurePosX' :)
