Hi, These tests are incorrect. Therefore, we will correct the tests.
The investigation concluded that all 13 failures are caused by expected floating-point precision differences introduced by reassociation enabled by commit #222302. No compiler malfunction was identified. The affected test cases contain overly strict or incorrect tolerance settings and should be updated accordingly.
Please ignore the mail. We'll update the test. We apologize for the false detection.
Best regards, Yasuyuki Ohno
