Yup, that definitely looks to be it; and the patch in
https://reviews.llvm.org/D70376 is better; thanks for the cross-reference.

Cool, it must have been switching from WeakVH to LVIValueHandle. The patch in
the other bug looks like it'll go in shortly, and it appears to fix the same
issue in a better way. I'll mark this as a duplicate; please re-open if D70376
doesn't actually fix it for you.
