glslc crash with segmentation fault

[zcorniere]

Hello ! I'm a recent Vulkan user, and I just ran into an issue. When I compile the fragment shader below, glslc trigger a segmentation fault (coredump.bin.zip)

#version 460
#extension GL_ARB_separate_shader_objects : enable
#extension GL_EXT_nonuniform_qualifier : enable

layout(location = 0) in vec3 fragColor;
layout(location = 1) in vec2 fragTextCoords;
layout(location = 2) flat in uint textureIndex;
layout(location = 3) in vec3 inFragPos;
layout(location = 4) in vec3 inNormal;

layout(location = 0) out vec4 outColor;

layout (push_constant) uniform constants {
    vec4 position;
	mat4 viewproj;
} cameraData;

layout(set = 1, binding = 0) uniform sampler2D texSampler[];

struct Material {
    vec3 ambientColor;
    vec3 diffuse;
    vec3 specular;
    float shininess;
};

layout (std140, set = 0, binding = 1) readonly buffer ObjectMaterials {
    Material materials[];
} objectMaterials;

vec4 computeBasicLight(Material mat) {
    float ambientStrength = 0.1;
    vec3 ambient = ambientStrength * mat.ambientColor;

    vec3 norm = normalize(inNormal);
    vec3 lightDir = normalize(vec3(11.0, 16.0, 24.0) - inFragPos);
    float diff = max(dot(norm, lightDir), 0.0);
    vec3 diffuse = diff * mat.diffuse;

    return vec4(ambient + diffuse, 1.0);
}

void main() {
    vec4 pixelColor = texture(texSampler[textureIndex], fragTextCoords);

    outColor = pixelColor * computeBasicLight(objectMaterials[0]);
}

glslc --version

I know that the function call computeBasicLight(objectMaterials[0]) is invalid, but shouldn't it print an error message ?
