This commit corrects C++ exception handling by enabling can_convert_eh to properly match std::nullptr_t exceptions with handlers declared to catch pointer or pointer-to-member types. This ensures that nullptr thrown as an exception can be caught by appropriate handlers, preventing potential runtime errors.
