Hello!

There is the following comment in sqlite3.h:
<code>
** If sqlite3_deserialize(D,S,P,N,M,F) fails for any reason and if the 
** SQLITE_DESERIALIZE_FREEONCLOSE bit is set in argument F, then
** [sqlite3_free()] is invoked on argument P prior to returning.

But this is not true - the only usage of pData is on the line:
<code>
    p->aData = pData;
<code>
Just before the successful exit, so the memory block is never freed on the function fail
