[Bug tree-optimization/102448] [12 Regression] wrong codegen in gcc in spec2017 since 24f99147b9264f8f7d9cfb2fa6bd431edfa252d2

--- Comment #2 from Tamar Christina <tnfchris at gcc dot gnu.org> ---
I have double checked the revision and it does start happening with it.

Though I can only reproduce it with -flto.  the codegen without lto seems the
same.

Any ideas how to debug further?
