--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
I believe we did run into this issue before. I'll have a closer look into the
failure mode but as both conversions need to be there I can't see how it
matches.
As said, I'll have a look (but yes, the lazy type matching of operand_equal_p
is a problem...)
