| # UBSan vptr blacklist. |
| # Function and type based blacklisting use a mangled name, and it is especially |
| # tricky to represent C++ types. For now, any possible changes by name manglings |

| # Identical layouts. |
| # If base and derived classes have identifical memory layouts (i.e., the same |
| # object size) and both have no virtual functions, we blacklist them as there |
| # would be not much security implications. |
