Run a Rust program and print a stack backtrace on failure (old)

rust-backtrace

#!/bin/bash

### NOTE ### You probably don't need this anymore!
# Just set RUST_BACKTRACE=1

# Usage: rust-backtrace ./my-rust-prog args...

exec gdb -batch -n -x /dev/fd/3 --args "$@" 3<<ENDGDB
set height 0
set breakpoint pending on

break rust_fail

commands 1
backtrace
quit
end

run
ENDGDB

Replace backtrace with thread apply all backtrace to get a stack from every thread.
