1 | // Test that AddressSanitizer does not re-animate dead globals when dead |
2 | // stripping is turned on. | |

4 | // This test verifies that an out-of-bounds access on a global variable is | |
5 | // detected after dead stripping has been performed. This proves that the | |
6 | // runtime is able to register globals in the __DATA,__asan_globals section. | |
