Hi, These tests are incorrect. Therefore, we will correct the tests.

Several Fujitsu Fortran tests fail during result comparison because their floating-point tolerances are too strict for single-precision arithmetic. For four of these tests, fpcmp-target uses a relative tolerance of 0x1.0p-51, which corresponds to double-precision accuracy and is too strict for the single-precision computations performed by the tests. The remaining test, 0676_0115, performs its own error check, but its absolute tolerance is also too strict for the observed single-precision result.

Please ignore the mail. We apologize for the false detection.

Best regards, Yasuyuki Ohno
