If we don't delete it manually assert will be thrown if SEC$DB_CREATORS returns a lot of records

Maybe it would be better to wrap |

There was a problem hiding this comment.
This is not required as every class inherited from pool_alloc has its instance zero-initialized at creation. But I prefer us being more explicit in this regard, so this is a good thing for master.

I found that if we try to write a lot of records to
RecordBuffer(>MIN_TEMP_BLOCK_SIZE) we start increasingm_tempCacheUsage. When we don't needRecordBufferanymore, it will be destroyed in~SnapshotData(), which will call~TempSpace()forFirebird::AutoPtr<TempSpace> space, and in~TempSpace()we will decreasem_tempCacheUsage.But this doesn't apply to
tra_dbcreators_listbecause we delete it by dropping the transaction pool, so destructor doesn't kick in and we don't decreasem_tempCacheUsage. All of this will causefb_assert(m_tempCacheUsage == 0)to be thrown, but I don't know what this might lead to in release build (nothing good, I suppose).This is also true for Firebird 5.0.
