Issue: Compiler Error - Unstable Fingerprints in mir_built.
Labels: I-ICE,T-compiler,C-bug

### Code

The codebase is getting larger, so its hard to provide a minimal verifiable snapshot, but the below code is what I believe to be the relevant sections. Interestingly after playing with the bug, it only ever popped up on the `entity_type("type")` in the builder. Other parameters showed no apparent issues.


```Rust
// ApiEndpoint.rs

#[derive(Debug, Builder, Clone)]
#[builder(setter(strip_option))]
pub struct ApiEndpoint {
    /// Dataset ID
    #[builder(default, setter(into))]
    dataset: Option<String>,
    #[builder(default, setter(into))]
    limit: Option<String>,
    /// Created at date, used for filtering by entities created after a specific date
    #[builder(default)]
    created_at: Option<DateTime<Utc>>,
    /// Filter by entity type
    #[builder(default, setter(into))]
    entity_type: Option<String>,
    #[builder(default)]
    tag: Option<String>,
}

impl ApiEndpoint {
    pub fn builder() -> ApiEndpointBuilder {
        ApiEndpointBuilder::default()
    }
}

impl<'a> Endpoint for ApiEndpoint {
//..//

    fn parameters(&self) -> QueryParams {
        let mut params = QueryParams::default();
        params
            .push_opt("limit", self.limit.as_ref())
            .push_opt("filter[datasets]", self.dataset.as_ref())
            .push_opt("filter[>created_at]", self.created_at)
            .push_opt("filter[type]", self.entity_type.as_ref())
            .push_opt("filter[tags]", self.tag.as_ref());

        params
    }
}

// endpoint.rs
pub trait Endpoint {
    /// HTTP Method to use for the endpoint
    fn method(&self) -> Method;
    /// Endpoint Path
    fn endpoint(&self) -> Cow<'static, str>;

    /// Endpoint Query parameters
    fn parameters(&self) -> QueryParams {
        QueryParams::default()
    }

    /// Body for endpoints that take body parameters.
    fn body(&self) -> Result<Option<(&'static str, Vec<u8>)>, crate::Error> {
        Ok(None)
    }
}

// main.rs
let entity_query = EntititesEndpoint::builder()
        .limit("5")
        .entity_type("type")
        .build()
        .unwrap()
        .query(&tip_client)
        .unwrap();
       
```
