No need to init it by NULL due to default constructor of the object:
explicit SharedRefPtr(T* ptr = NULL)
So, please undo the change.

Agree.
(Just for rare case when 'temp_table_name' is empty string.)
| table_name = temp_table_name; | ||
| table = keyspace->get_table(table_name); | ||
| if (!table) continue; | ||
| table->clear_indexes(); |

The main problem is here. If the table is not found the 'table_name' must be reset!
So, the line
if (!table) continue;
must be changed into:
if (!table) { table_name.clear(); continue; }

There is a chance meta table is uninitialized. A segment fault will occur.
