internal compiler error on 1.4.0-dev for i686-pc-windows-gnu

[hebiyan]

I tried the cross-compilation for windows following procedures on this page.
Using Rust in Wine as a sort of cross-compiler
In procedure No.3, I got an internal compiler error, like that.

$ RUST_BACKTRACE=1 /opt/local/bin/rustc -C linker=~/bin/gccwrapper --target i686-pc-windows-gnu test_cross/src/main.rs
ERROR:rbml::reader: failed to find block with tag 42
error: internal compiler error: unexpected panic
note: the compiler unexpectedly panicked. this is a bug.

Sorry for poor my english.
Thank you.

Currently the compiler can't link against artifacts produced by a different version of the compiler, so it may be the case that the libraries for i686-pc-windows-gnu are produced by a different version than 5aca49c69 (the host compiler). Syncing the two together should cause this to go away.

Otherwise though I believe this is a dupe of #27645 so closing in favor of that.
