> That `@noinline` function should probably have a type signature that forces specialization, in order to make the code GPU compatible. Maybe open an issue on [StaticArraytsl.jl](https://juliahub.com/ui/Packages/StaticArraytsl)?

if I force specialization of the function `StaticArrays.dimension_mismatch_fail` on a local checkout ouf `StaticArrays`, I just get another error:

```julia
Reason: unsupported dynamic function invocation (call to print_to_string(xs...) @ Base strings/io.jl:137)
