# backtrace-on-stack-overflow

By default, Rust aborts on stackoverflow without printing a backtrace:

```console

λ bat src/main.rs

fn main() {

    f(92)

}

fn f(x: u64) {

    f(x)

}

λ cargo run

    Finished dev [unoptimized + debuginfo] target(s) in 0.00s

     Running `target/debug/so`

thread 'main' has overflowed its stack

fatal runtime error: stack overflow

fish: Job 1, 'cargo run' terminated by signal SIGABRT (Abort)

```

This crate fixes this:

```console

λ bat src/main.rs

fn main() {

    unsafe { backtrace_on_stack_overflow::enable() };

    f(92)

}

fn f(x: u64) {

    f(x)

}

λ cargo run

    Finished dev [unoptimized + debuginfo] target(s) in 0.01s

     Running `target/debug/so`

This crate works for debugging, but is unsuited for being enabled in production.
