 > Oh so if that's all true, another question, what version of rustc is
 this using?

 The one at 6b7b6b63a928479a29d9fc1282e553e409c66934 with a bunch of
 patches for the LLVM bisecting.

 > And additionally, y'all are seeing reproducibility issues on the current
 nightly release of Rust, right? (latest LLVM we're using as well as latest
 rustc). IIRC though those issues haven't been reduced yet and it's
 suspected that this one is the cause?

 I *think* we could be lucky in that it got fixed more or less recently
 during the upgrade to LLVM 7. The result is not conclusive yet as there
 popped another reproducibility issue up (see: comment:28).

 So, I'd suggest waiting with filing an LLVM bug until I have bisected that
 other issue.
