Reduced the code from comment #2 further:
struct Bytecode
{
int raw;
}
Bytecode[] getIr()
{
Bytecode[] ir;
ir ~= Bytecode(42);
ir ~= ir[0 .. 1]; // add .dup and CTFE gets it
assert(&ir[0] != &ir[1]); // fails in CTFE
ir[0].raw = 13; // overwrites both ir[0] and ir[1]
assert(ir[0].raw == 13);
assert(ir[1].raw == 42); // fails in CTFE
return ir;
}
void main()
{
enum expected = [Bytecode(13), Bytecode(42)];
assert(getIr() == expected); // passes
static assert(getIr() == expected); // fails
}
