Hi, I took a look. This is probably caused by a floating-point arithmetic error.
The Fortran source program is https://github.com/fujitsu/compiler-test-suite/blob/main/Fortran/0354/0354_0334.F90 . The compilation flags are `-O3 -ffast-math`. Changing `1.0E-6` to `1.0E-3` in the first line resolves this failure. Adding `-fno-associative-math` also resolves this failure. If this floating-point arithmetic error is intended to occur, you don't need to investigate it.
