Trying to build something big (rust-snake) with my new rustc 1.6 (i686-unknown-linux-gnu from 2015-11-29, generating code for pentium2) ended on the rocks (pun intended):

I was using cargo-bake to compile.

[jdm]

Should be fixed by #30116.

[MagaTailor]

Ok, thanks - I was trying to find a similar issue but didn't hit that one.

[alexcrichton]

Yeah I think this was fixed there, so closing.
