    <thetext>Running https://gpuweb.github.io/cts/standalone/?q=webgpu:shader,validation,expression,call,builtin,bitcast:bad_type_nonconstructible:var=%22t%22;direction=%22from%22

crashes on a release assert because texture_depth_2d can not be bitcast:

    @group(0) @binding(0) var s: sampler;
    @group(0) @binding(1) var t: texture_depth_2d;
    @group(0) @binding(2) var&lt;storage&gt; b: array&lt;i32&gt;;
    var&lt;private&gt; v: i32;
    @compute @workgroup_size(1)
    fn main() {
      let p = &amp;v;
      let x = bitcast&lt;i32&gt;(t);
    }
    

instead of release assert, we could probably return an error here since the wgsl is not valid</thetext>
