[BUG]: Compiler crashes while analyzing function signature after variadic arguments about mojo HOT 1 CLOSED

@kishmakov Thank you for opening this ticket! The root cause of the problem was a known limitation in mojo: variadic and optional arguments (i.e. arguments with default values) could not be declared in the same signature. This limitation will be lifted in an upcoming release, which should prevent the crash. Then your first example will produce the expected error, i.e.

fn test(
    first_args: Int, *second_args: Int, another_arg: Int = 1, other_arg: Int
) -> Int:
    return another_arg

yields

error: required keyword-only argument follows optional keyword-only argument
    first_args: Int, *second_args: Int, another_arg: Int = 1, other_arg: Int

and the second example will just work. Please open separate tickets if you run into problems with this feature!
