Segmentation fault with multiple block partials

[rplopes]

I'm getting segmentation fault when working with more than one partial using the block notation.

I've managed to isolate the issue into the following code:

use handlebars::Handlebars;
use std::collections::HashMap;

fn main() {
    let mut handlebars = Handlebars::new();
    let template1 = "<outer>{{> @partial-block }}</outer>";
    let template2 = "{{#> t1 }}<inner>{{> @partial-block }}</inner>{{/ t1 }}";
    let template3 = "{{#> t2 }}Hello{{/ t2 }}";

    handlebars
       .register_template_string("t1", &template1)
       .unwrap();
    handlebars
       .register_template_string("t2", &template2)
       .unwrap();

    let mut data = HashMap::new();
    data.insert("hello".to_string(), "world");

    let page = handlebars.render_template(&template3, &data).unwrap();
    println!("{}", page);
}

Running this code, what I expected:

<outer><inner>Hello</inner></outer>

However, this is what I'm getting instead:

[2]    1953 segmentation fault  cargo run

It seems stack overflow happened for @partial-block. Thank you for reporting and I will look into this.

@rplopes could you please try fix in #401 if it works for your case?

I can confirm it works great indeed, awesome work 👍

@rplopes Thank you again for verifying and your test case has been super helpful.
