// 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.
