If you could dig up that testcase, it would be quite useful!

I couldn't find any definitive proof that upstream GCC fixed this bug
(closest I could find is [1]) at some point over the past decade or so,
but I figured I'd start with a clean slate and only forward-port the
workaround patch if it turned out to be necessary. And then pester the
GCC folks about it. :)
