Bug 1801 – Const structs should be assignable to non-const variables unless they contain references

For structs not containing any reference values (like pointers, class references, arrays etc.) and have not fields which are not assignable for this reason (structs/unions with references). // should be allowed, pure copy: struct S { int x; } const S s_const = {0}; S s_mutable = s_const; // currently not allowed On a related note, initialization of constant variables should be possible, even if the source value is constant: struct S1 { int x; } struct S2 { S1 s1; } const S1 s1_const = {0}; const S2 s2_const = {s1_const}; // currently not allowed
