| // Address Sanitizer doesn't instrument weak symbols on Linux. When a key |
| // function is defined for bad_function_call's vtable, its typeinfo and vtable |
| // will be defined as strong symbols in the library and weak symbols in other |
| // translation units. Only the strong symbol will be instrumented, increasing |
| // its size (due to the redzone) and leading to a serious ODR violation |
| // resulting in a crash. |
