Hi, This test is incorrect.
0196_0003.c contains intentional undefined behavior and should not be used as a runtime correctness test. The observed SIGSEGV is a valid consequence of the program's undefined behavior, and the test should be converted to a compile-only test to avoid environment-dependent failures.
Please ignore the mail. We'll update the test. We apologize for the false detection.
Best regards, Yasuyuki Ohno
