First, you need to run rustc -g hello.rs -- the -g flag tells rustc to
generate debuginfo.
After that, you can use gdb on the resulting executable and set
breakpoints, get a stack trace (with bt), and possibly some of the
other things you usually do with gdb. It's useful to know that if you
set a break on upcall_fail , then you'll break at any point where your
program calls the fail!() macro or has an assertion failure arising
from assert!().
Cheers,
