Array::new() segfaults on cargo test

[wshatch]

When I run cargo test on

extern crate ruru;

#[cfg(test)]
mod tests {
  use ruru::{Array};
    #[test]
    fn it_works() {
      let array = Array::new();
    }   
}

I get the following results

VM needed to be initiated

extern crate ruru;

#[cfg(test)]
mod tests {
  use ruru::{Array, VM};
    #[test]
    fn it_works() {
      VM::init();
      let array = Array::new();
    }
