Description dave287091 2021-11-14 22:43:08 UTC 
The following valid C code fails to compile:

// staticvar.c
int x = 0; 
int* y = &x; // ok

struct Foo {
    int x;
};

struct Foo f = {3};
int* z = &f.x; // error

The message is:

staticvar.c(10): Error: static variable `f` cannot be read at compile time

The equivalent D code also fails to compile, but I don’t know if that is according to spec or not.
