Description
Building Rust fails while compiling bootstrap. I managed to narrow it down while compiling beta (5c5be09) and setting build.rustc.
rustc 1.29.0-nightly (64f7de9 2018-07-12)
doesn't work
rustc 1.29.0-nightly (e5f6498 2018-07-10)
does work. So I believe it's a bug in LLVM 7
Maybe it's fixed by llvm-mirror/llvm@57aa5d9 in LLVM 7.0 RC2 but I haven't been able to try it yet.
Thread 30 "rustc" received signal SIGSEGV, Segmentation fault.

Backtrace stopped: previous frame identical to this frame (corrupt stack?)
It looks similar to #52884 but that has been fixed as I understand (I also get the problem using 'rustc 1.29.0-beta.7 (49720ea 2018-08-26)')
