The offending bit of code seems to be `
pub fn name_string<'a, 'c>() -> impl Parser<'a, 'c, AmlName>
where
'c: 'a,
{
/*
* NameString := <RootChar('') NamePath> |
* PrefixPath := Nothing | <'^' PrefixPath>
*/
let root_name_string = opcode(ROOT_CHAR).then(name_path()).map(|((), ref name_path)| {
let mut name = alloc::vec![NameComponent::Root];
name.extend_from_slice(name_path);
Ok(AmlName(name))
});

// TODO: combinator to select a parser based on a peeked byte?
comment_scope_verbose("NameString", move |input: &'a [u8], context| {
    let first_char = match input.first() {
        Some(&c) => c,
        None => return Err((input, context, AmlError::UnexpectedEndOfStream)),
    };

    // TODO: parse <PrefixPath NamePath> where there are actually PrefixChars
    match first_char {
        ROOT_CHAR => root_name_string.parse(input, context),
        PREFIX_CHAR => unimplemented!(),
        _ => name_path().map(|path| Ok(AmlName(path))).parse(input, context),
    }
})

}`

Tried to run a freshly cloned (git clone https://github.com/64/solstice.git) copy of the project. Build succeeds (cargo xbuild) but run (cargo xrun) fails with
