The GLSL compiler aborts when validating the IR for this shader: void main() { vec2 var; gl_FragColor = vec4(var, vec2(1.0)); } Debug output: Assignment count of LHS write mask channels enabled not matching RHS vector size (2 LHS, 1 RHS). (assign (constant bool (1)) (zw) (var_ref vec_ctor@0x9ed8ad0) (constant float (1.000000)) )
