Steps to reproduce:

(1) Run LibreOffice with command-line parameter --base to create (but
    do not register) /tmp/a1.odb with embedded firebird database.
    Program presents window "a1.odb".

(2) Take menu options Tools > "SQL...".  Program presents window
    "Execute SQL Statement".

(3) Paste command 
        create table t1 ( id integer not null, field1 varchar(20) not
        null );
    into "Command to Execute" and click <Execute>.  LO reports status:
    "1: Command executed successfully."

(4) Paste command
        CREATE TRIGGER T1_BI FOR T1
        ACTIVE BEFORE INSERT POSITION 0
        AS BEGIN
        if (new.id IS null) THEN new.id =
        GEN_ID(GEN_T1ID, 1);
        END
    into "Command to execute" and click <Execute>.  LO reports status:
        2: firebird_sdbc error:
        *invalid request BLR at offset 23
        *generator GEN_T1ID is not defined
        caused by
        'isc_commit_transaction'
    This is entirely to be expected.  (It was an accident the first
    time I did it.)

(5) Close window "Execute SQL Statement".  Program returns focus to
    window "a1.odb".

(6) Take menu options File > Quit.  Program presents prompt "Save
    Document?".

(7) Click <Save>.  Program fails with SIGABRT; the .odb is not
    updated.


Note that the failure is somewhat fragile:

(*) Not every SQL error in place of step (4) is followed by a crash.
    On the other hand, I have seen failures even when step (4) was
    followed by perfectly good SQL commands.

(*) I am using a debug build.  Unless the problem is seen in a
    non-debug build, I would presume that the debug build is part of
    the cause of the crash.
