Input (invalid.circom):

pragma circom 2.0.0;

function funA(){
    var out[1];
    /*return*/ out;
}

template TempA() {
    var result[1] = funA();
}

component main = TempA();

Command:

cargo build --release
target/release/circom invalid.circom

Outcome:

thread 'main' panicked at 'internal error: entered unreachable code', type_analysis/src/analyzers/symbol_analysis.rs:167:47

Hi! We have solved this issue in our last commits, now the compilation of the circuit returns the following error message:

error[P1012]: illegal expression
  ┌─ "aux.circom":5:19
  │
5 │     /*return*/ out;
  │                   ^ here

previous errors were found

Thank you for reporting the issue
