Artelia (cc'ing rust-dev)-
FYI: There is no '-g' flag, at least not in Rust 0.6. According to the
#rust IRC channel, the correct flag is now "-Z debug-info"
From the #rust IRC channel:

Hi, I know that if I have the following basic program :
***********
///hello.rs
fn main(){
io::println("Hello");
}
***********
then the command :
rustc hello.rs
produces an executable called hello which I can then run in ubuntu,
How would I compile it so that I can then use gdb to debug, for example to
set a breakpoint on println? So far I have only found the following as an
example of someone using GDB to debug Rust :
https://github.com/mozilla/rust/issues/1174 . Thanks.
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,
Tim
