--- Comment #4 from Martin Liška <marxin at gcc dot gnu.org> ---
Confirmed, I see Fortran discrepancy since r243830:

$ gfortran pr82869-2.f90  -O0 && ./a.out 
 (Expect F F)  F F
$ gfortran pr82869-2.f90  -O2 && ./a.out 
 (Expect F F)  T T

Comparison of sanitized and not sanitized tree dump looks the same (modulo
memory checks).
