Segmentation Fault When Using Anonymous Struct Literal Assignment

[defaultgnome]

Zig Version

0.14.0

Steps to Reproduce and Observed Behavior

1. Create a new Zig project (I've used zig init).
2. Place the following minimal code into your main.zig:

fn createVec(x: f32, y: f32, z: f32) [3]f32 {
    return .{ x, y, z };
}

var camera = .{
    .pos = createVec(0, 0, 0),
};

pub fn main() !void {
    camera.pos = createVec(0, 1, 0);
}

3. Build and run the project using zig build run.

Observed Behavior
The program terminates with a segmentation fault:

Segmentation fault at address 0xaaaaaaaaaaaaaaaa
aborting due to recursive panic
run
└─ run zig_seg_fault_anony_lit_struct failure
error: the following command terminated unexpectedly:

Build Summary: 3/5 steps succeeded; 1 failed
run transitive failure
└─ run zig_seg_fault_anony_lit_struct failure
error: the following build command failed with exit code 1:

Expected Behavior

Now I understand that Anonymous Struct Literals create comptime fields that can't be modified.

But should it compile at all?

Correctly caused a compile error in 0.13:

test.zig:10:11: error: cannot store runtime value in compile time variable
    camera.pos = createVec(0, 1, 0);
