bus error on usage of rusqlite with spatialite extension - sqlite

Question

I'm seeing a bus error on cargo run when attempting to load the spatialite extension with rusqlite:
Finished dev [unoptimized + debuginfo] target(s) in 1.19s
Running `target/debug/rust-spatialite-example`
[1] 33253 bus error cargo run --verbose
My suspicion is that there's a mismatch of sqlite version and spatialite and that they need to be built together rather than using the bundled feature of rusqlite, though it seems like that'd result in a different error?
Here's how things are set up:
Cargo.toml
[package]
name = "rust-spatialite-example"
version = "0.0.0"
edition = "2021"
# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html
[dependencies]
rusqlite = { version = "0.28.0", features = ["load_extension", "bundled"] }
init.sql
CREATE TABLE place (
id INTEGER PRIMARY KEY,
name TEXT NOT NULL
);
SELECT AddGeometryColumn('place', 'geom', 4326, 'POINT', 'XY', 0);
SELECT CreateSpatialIndex('place', 'geom');
main.rs
use rusqlite::{Connection, Result, LoadExtensionGuard};
#[derive(Debug)]
struct Place {
id: i32,
name: String,
geom: String,
}
fn load_spatialite(conn: &Connection) -> Result<()> {
unsafe {
let _guard = LoadExtensionGuard::new(conn)?;
conn.load_extension("/opt/homebrew/Cellar/libspatialite/5.0.1_2/lib/mod_spatialite", None)
}
}
fn main() -> Result<()> {
let conn = Connection::open("./geo.db")?;
load_spatialite(&conn)?;
// ... sql statements that aren't executed
Ok(())
}
Running:
cat init.sql | spatialite geo.db
cargo run
The mod_spatialite path is correct (there's an expected SqliteFailure error when that path is wrong). I tried explicitly setting sqlite3_modspatialite_init as the entry point and the behavior stayed the same.
