Could you also keep a small test that doesn't need REAL(16)? My suggestion missed the `flang-supports-f128-math` requirement: the Linux premerge run for this revision reports `fold-out_of_range.f90` as unsupported ("Missing required feature(s): flang-supports-f128-math"), so the new kind-8 RUN line isn't exercised there. The `fold-out-of-range-integer-8.f90` you had before would do; it aborts without the fix and passes with it.
