## Message

```
wasm linking: handle unreachable call_indirect

The compiler crashed when we tried to call a function pointer for which
the type signature does not match any function body or function import
in the entire wasm executable, because there is no way to create a
reference to a function without it being in the function table or import
table. Solution is to make this instruction lower to unreachable.

```
