<div>
<pre>The following program builds under c++20 in c++ but not with CUDA:
```
struct A {
constexpr ~A() {
// some body is needed for the issue to occur
;
}
};
constexpr A a;
```
It fails to build with "error: dynamic initialization is not supported for
__device__, __constant__, and __shared__ variables."
I think the desired behavior would be for this to be valid CUDA.</pre>
