Incorrect parsing behavior in multi-if scrope

input shader

varying vec2 v_texcoordOut;
uniform sampler2D s_texture;
uniform float u_degree;
uniform float u_degree2;

void main(void)
{
    vec2 texcoord = v_texcoordOut;
    if(u_degree > 0.001)
    {
        if(u_degree2 > 0.8)
        {
            texcoord.x += 0.1;
        }
        else if(u_degree2 >0.5)
        {
            texcoord.y += 0.1;
        }
    }
    gl_FragColor = texture2D(s_texture, texcoord);
}

missing scrope in ""if(u_degree>.001)""

I think the output is correct, the curly braces are not needed here.

Some machines produce compilation errors because of this approach

Can you give more information on your setup? What tool is compiling the code? Have you considered filing a bug against that tool?

As far as I can tell, the syntax is not ambiguous, it's properly defined in the spec (at least for GLSL).
