Running this shader in geometry stage, it segfaults:

#version 330

layout(points) in;
layout(points, max_vertices = 1) out;

in gl_PerVertex {
    vec4 gl_Position;
    float gl_PointSize;
    float gl_ClipDistance[];
} gl_in[];

in vec4 v_colour[];
out vec4 g_colour;

void main() {
  for(int i = 0; i < 1; i++) {
    gl_Position = gl_in[i].gl_Position;
    gl_PrimitiveID = gl_PrimitiveIDIn;
    /* TODO report bug */
    g_colour = v_colour[i];
    EmitVertex();
  }
  EndPrimitive();
}
