Compiler encountered an unexpected error (unreachable) with a two-dimensional array and [*] syntax #2505
Description
The compiler encountered an unexpected error with a two-dimensional array and [*] syntax
Minimal example
// char[1][*] a = { [0] = { [0] = 1 } }; // works as expected
// char[1][1] b = { [0] = { [0] = 1 } }; // works as expected
// char[*][*] c = { [0] = { [0] = 1 } }; // reports a cast error
char[*][1] d = { [0] = { [0] = 1 } }; // compiler encountered unreachable code
fn void main() {}This creates the following compiler error:
⚠️ The compiler encountered an unexpected error: "Should be unreachable".
