Some panics cause RStudio to crash

[mhovd]

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.

/// 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.
