<div>
<pre>While running the GLES3 dEQP tests on ANGLE the Intel Mesa driver, many of the
tests in dEQP-GLES3.functional.shaders.conversions.matrix_combine.* segfault in
the driver in glLinkProgram.
This was running on an Ubuntu variant with the following:
OpenGL renderer string: Mesa DRI Intel(R) HD Graphics 5500 (Broadwell GT2)
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.5.9
OpenGL core profile shading language version string: 3.30
I was able to repro the crash using the following vertex shader:
#version 330
in vec4 vPosition;
in vec3 v1;
in vec3 v2;
in vec2 v3;
out mat4x2 out0;
void main(){
(gl_Position = vPosition);
(out0 = mat4x2(v1, v2, v3));
}
and the following fragment shader:
#version 330
in mat4x2 out0;
out vec4 FragColor;
void main(){
(FragColor = vec4(1.0, out0[1][1], 0.0, 1.0));
}</pre>
