It should be possible to do this as they are in different scopes and should've be different than declaring a variable in different scopes.
Issue 18266 was resolved but only "half" fixed - i.e. the ICE part. So I'm creating this one to keep track of the other half of that issue.

I would like to add, that this also blocks the usage of multiple static variables with the same name inside one function, not just type definitions.
void main() {
{
__gshared int x = 0;
}
{
__gshared float x = 1;
}
}
This is used by libraries like Dear ImGui.
