glslangValidator incorrectly gives error on use of member name length

I have a compute shader that looks like

```
#version 450

layout (local_size_x = 32) in;

struct A{
uint length;
uint contents[7];
};

restrict layout(std430, set = 0, binding = 2) buffer SuperBuffer{
A collision_grid[1024];
};

void main()
{
uint gID = gl_GlobalInvocationID.x;
atomicAdd(collision_grid[gID].length, 1);
}
```

When I run `glslc my_shader.comp -o o.spv` I get `Segmentation fault (core dumped)`. However, if I rename `length` variable to something else, the compilation passes successfully.

My compiler version

```
$ glslc --version
