The relevant commit from mingw-w64 is probably https://github.com/mirror/mingw-w64/commit/a0ee49ec60f8a2a54e9991ef37501f62cfb07bdd. I think we are mixing mingw-w64 library versions. Old crt2.o with newer libmsvcrt.a.

Commit https://github.com/rust-lang/rust/commit/80d6ed2d8b2f76cd526d2449c70a1a6af315c114#diff-3e203f016947a52e3f1fad3967027e7e (@alexcrichton) removed the downloading of rust-mingw which is a copy of mingw and libraries that should work with crt2.o, and other such libraries, that are included in rust-std.

Extracting the matching rust-mingw files into the stage0 manually made the build continue. (Not sure if it will finish, it can take a while... 😛). EDIT: It finished.

Hm ok, we could try to add that download back in, I sort of forget at this point why it was removed..

I am running Arch Linux, rustc 1.31.0-nightly installed using rustup.
I am using mingw-w64-crt-bin precompiled package from AUR.
I am experiencing the same issue.
To fix this, I tried this and it somehow worked :D

cd /home/farzeen/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/x86_64-pc-windows-gnu/lib/
mv crt2.o crt2.o.bak
cp /usr/x86_64-w64-mingw32/lib/crt2.o ./

I was compiling a Hello World application using gtk-rs.
