Yes I do. Even if I did not free this this would not make a
difference to the leak I am seeing. The sqlda is allocated in my
software as your example indicates by calling mallloc/free. The larg
memory growth I am encountering is in the IBServer.exe so this is
memory allocated by the server.

Note I can make the examples do this simply by putting a loop around
the transaction.
