internal compiler error: unexpected failure

[mneumann]

mneumann@box:~/rust-redis$ rustc -v
rustc 0.5 (dbc52ce 2012-12-14 16:50:08 -0800)
host: x86_64-unknown-linux-gnu

When I compile the file:

https://github.com/mneumann/rust-redis/blob/master/redis-fails.rs

I get the following error:

redis.rs:104:6: 104:11 warning: unused variable: cmd
redis.rs:104 let cmd = cmd_to_str(cmd);
