Issue ID: 10342
Summary: Potential Memory Leak in function mdb_txn_begin
Product: OpenLDAP
Version: unspecified

OS: All
Status: UNCONFIRMED

Free txn->mt_u.dirty_list before freeing txn
The function `mdb_txn_begin` allocates the dirty list via
```c
txn->mt_u.dirty_list = malloc(sizeof(MDB_ID2) * MDB_IDL_UM_SIZE);
```
Later, when `txn != env->me_txn0`, it calls
```c
free(txn);
```
without first freeing `txn->mt_u.dirty_list`. This orphaned allocation leads to
a memory leak.
