@alexcrichton, do you know if https://reviews.llvm.org/rL319126 is part of our LLVM? It seems to be related. |
|
@alexcrichton, nevermind. Just saw that our code does include that fix. |

If you need a compiler with debuginfo, you can compile it up to the crash and then set both |

I am also hitting this when running |

And that means I am hitting it when building stage 0 artifacts. A few days ago I was hitting it only when building stage 1 artifacts, but I updated my rustc repo today and now it's on stage 0 artifacts too :( |

…lexcrichton Work around LLVM debuginfo problem in librustc_driver. Works around a problem (rust-lang#48910) with global variable debuginfo generation for `rustc_driver::get_trans::LOAD` by applying `#[no_debug]` to it (which just disables debuginfo generation for that variable). This way we can build the compiler with debuginfo again. Since the problem is also present in beta, this workaround might have to be backported. r? @alexcrichton

I tried to compile Rust myself, got an error at stage2 (I think)
Search yielded similar issues(though none had "fragment covers entire variable") which led me to believe this might be an actual issue rather than a side effect of my (potentially poorly)overclocking of the CPU.
Here's the gist of what I tried and the error it gave:
Rustc source was at this HEAD:
commit 3edb3cc (HEAD -> master, origin/master, origin/HEAD)
Date: Sat Mar 10 03:38:19 2018 +0000
EDIT: forgot to mention cargo version:
