ISSUE:       5551
TITLE:       Attempt to create database with running trace leads to consistency check (cannot find tip page (165), file: tra.cpp line: 2233)
DESCRIPTION:
    1. Get the content of firebird.log before test.
    2. Make config file and launch trace session, with separate logging of its STDOUT and STDERR.
    3. Make DDLfile and run ISQL, with separate logging of its STDOUT and STDERR.
    4. Stop trace session
    5. Get the content of firebird.log after test.
    6. Ensure that files which should store STDERR results are empty.
    7. Ensure that there is no difference in the content of firebird.log.
