Some panics cause RStudio to crash

As stated in the title, some panics cause RStudio to crash. I have had a hard time creating a minimal example, as the following code does NOT cause RStudio to crash. These are placed in the `lib.rs` of a new R `rextendr` project. ```rust /// Just panic /// @export #[extendr] fn just_panic() { panic!("at the disco"); } /// Create a panic due to index out of bounds /// @export #[extendr] fn index_out_of_bounds() { let vec = vec![10, 20, 30, 40, 50]; let _value = vec[7]; // This will panic with index out of bounds println!("This line should never be reached!"); } ``` Similar code with panics in spawned threads (either using `std::thread` or `rayon` parallell iterators) does not crash. What _does_ cause our RStudio to crash are panics in third-party crates, where the panic occurs because of an out-of-bounds error in a parallell iterator, hence the example above. @CGMossa was able to reproduce, and could probably supply a better example.
