--- Comment #2 from Sanjay Patel <spatel+llvm at rotateright.com> ---
I remembered that we added remarks for this kind of situation:
https://reviews.llvm.org/rL294208

...and it works from -instsimplify:

$ ./opt -instsimplify 35846.ll -S -pass-remarks-analysis=.*
remark: <unknown>:0:0: Detected conflicting code assumptions. Program may have
undefined behavior, or compiler may have internal error.

...but not with -instcombine, so maybe the simplify query isn't populated
correctly in instcombine.

But this should be fixed with:
https://reviews.llvm.org/rL322104
