SIGSEGV instead of a syntax error

[snakeru]

Hi there!

I stumbled upon an issue caused by my own stupidity. Luckily a chat-bot was able to identify a syntax error for me, so here is a bug report for you :)

If I try to use this shader:

@compute @workgroup_size(64)
fn main(@builtin(global_invocation_id) global_id: vec3<u32>) {
    let diff = vec2<f32>(1.0, 1.0);
    let dist2 = dot(diff);
}

Then my go program crashes with SIGSEGV:

$ ./run
Can't open bumblebee display.
2026/05/05 16:20:13 INFO adapter selected name="Intel(R) UHD Graphics (TGL GT1)" type=IntegratedGPU
SIGSEGV: segmentation violation

The problem, apparently, is in the fact that dot-product requires two arguments and I gave it only one (I was trying to find the distance square).

So the bugfix for me was to do

    let dist2 = dot(diff, diff);
