Illegal instruction (core dumped)

[yeahnoob]

After $cargo build, run & get this error.
How deal with it?

$ ./target/iota
Illegal instruction (core dumped)

PS.
Ubuntu 14.04 LTS x64;
Nightly Build's rustc and cargo.

Same here on OSX 10.9.5.

$ target/iota
[1]    97292 illegal hardware instruction  target/iota

[gchp]

Yeah, same for me. Investigating now

Seems to be coming from this https://github.com/gchp/iota/blob/master/src/main.rs#L53-L56

I wonder if this has to do with some changes in http://github.com/nsf/termbox that landed yesterday. Rustbox relies on this, so it could be that some of those changes have messed things up for us.

Two fields were added tb_event struct.. maybe that?

Calling tb_select_input_mode before tb_init. tb_select_input_mode calls bytebuffer_puts and bytebuffer_flush, but buffers are not initialized before tb_init is called.

PS: use rust-gdb, it rocks.

Heh, I had actually pointed this out earlier after your commit, but at the time it wasn't causing any issues so it wasn't urgent.

gchp/rustbox@7707700

In the future we should probably be more proactive about potential future incompatibilities like that. It's kinda hard to know which ones are going to end up being important.

I was having trouble replicating the problem until I updated the rustc nightly. It was only ~1 day old, but with the compiler update I now get the illegal instruction. It looks like this is one of those cases where it probably should never have worked in the first place.

[gchp]

Yup, @suhr and @pythonesque were right!

I've update released rustbox 0.2.14 which fixed this. Should be good to go!
