Bug 23109 – ICE: AssertError@src/dmd/dclass.d(449): Assertion failure

--- module dmd.arraytypes; import dmd.statement; import dmd.func; struct Array(T) { T[] data; enum SMALLARRAYCAP = 1; T[SMALLARRAYCAP] smallarray; } alias Ensures = Array!Ensure; --- module dmd.func; import dmd.arraytypes; import dmd.statement; struct Ensure { Statement ensure; Ensures* arraySyntaxCopy() { } } --- module dmd.statement import dmd.func; class Statement {} ---

The ICE itself occurs when druntime 2.076 is being pulled in by a dmd 2.100 compiler. Minimal object.d: --- module object; alias size_t = typeof(int.sizeof); class Object { } auto opEquals(Object ) { } class TypeInfo { } class TypeInfo_Const { } bool _xopEquals() { } bool __equals(T1, T2)(T1[] lhs, T2[] rhs) { static at(R)(R[] r, size_t i) { return r.ptr[i]; } foreach (u; 0 .. lhs.length) if (at(lhs, u) != at(rhs, u)) return ; } ---
