Problem with matrix in Flash

[romamik]

Render code:

        var projection = FastMatrix4.orthogonalProjection( -framebuffer.width / 4, framebuffer.width / 4, framebuffer.height / 4, -framebuffer.height / 4, 0.1, 1000);
        var model = FastMatrix4.rotation(0, angle * Math.PI / 180, 0).multmat(FastMatrix4.translation( -50, -50, 0));
        var matrix = projection.multmat(model);

        var g4 = framebuffer.g4;
        g4.begin();
        g4.clear(Color.Black);

        g4.setVertexBuffer(vertexBuffer);
        g4.setIndexBuffer(indexBuffer);
        g4.setPipeline(shaderPipeline);
        g4.setTexture(textureLocation, Assets.images.bitmap);
        g4.setMatrix(projectionLocation, matrix);
        g4.setTextureParameters(textureLocation, TextureAddressing.Clamp, TextureAddressing.Clamp, TextureFilter.LinearFilter, TextureFilter.LinearFilter, MipMapFilter.NoMipFilter);
        g4.drawIndexedVertices(0, 6);
        g4.setTexture(textureLocation, null);
        g4.end();

And in flash for angles from 90 to 270 my picture dissappears. I also tested in windows and HTML5 and it's ok. I'm using shaders used by Graphics2.

Manually applying the same matrix and setting shader matrix to identity makes it work...

So I made more simple example and found that the problem is in the agal code.

matrixwtf2.zip

GLSL source:

#version 100

attribute vec3 vertexPosition;
uniform mat4 projectionMatrix;

void kore() {
    gl_Position = projectionMatrix * vec4(vertexPosition, 1.0);
}

Generated ".vert.agal" file:

{
    "varnames": {
        "gl_Position": "vt0",
        "projectionMatrix": "vc0",
        "vertexPosition": "va0"
    },
    "consts": {
        "vc0": [0.5],
        "vc1": [0.5],
        "vc2": [0.5],
        "vc3": [0.5],
        "vc4": [1.0, 1.0, 1.0, 1.0]
    },
    "agalasm": "mov vt0, vc0\nmov vt1, vc1\nmov vt2, vc2\nmov vt3, vc3\nmov vt4, va0\nmov vt5, vt4.xxxx\nmov vt6, vt4.yyyy\nmov vt4, vt4.zzzz\nmov vt5.x, vt5.x\nmov vt5.y, vt6.y\nmov vt5.z, vt4.z\nmov vt5.w, vc4.w\nm44 vt0, vt5, vt0\nmov vt0, vt0\nadd vt1.xxxx, vt0.zzzz, vt0.wwww\nmul vt0.z, vc0.x, vt1.x\nmov op, vt0\n",
} 

And when I change agal to

    "agalasm": "m44 op,va0,vc0\n"

Everything begin to work correctly.
