Comment 3 Yuri Victorovich freebsd_committer freebsd_triage 2018-08-14 02:06:06 UTC 
This looks like a clang/llvm internal failure to me:

> PHI nodes not grouped at top of basic block!
>   %e1.sroa.20.0 = phi <2 x float> [ %29, %if.then.i ], [ %11, %entry ]

It should be reported to the llvm project as a regression.

Another port bundles VTK, so Clang crashes pretty much the same way.

Comment 5 Dimitry Andric freebsd_committer freebsd_triage 2018-09-16 08:10:03 UTC 
This was fixed upstream in https://reviews.llvm.org/rL339853, for https://bugs.llvm.org/show_bug.cgi?id=38418, and merged to the release_70 branch in https://reviews.llvm.org/rL339853.

So the fix came in with base 338014, where I merged upstream release_70 r339999.
