ISSUE:       6019
TITLE:       Regression: FB crashes when trying to recreate table that is in use by DML (3.0.3; 3.0.4; 4.0.0)
DESCRIPTION:
  A bug was detected during implementation of test for CORE-5754: FB crashed with currpupting database
  after we run test script two times (letter to dimitr et al 20-feb-18 13:52). Moreover, gfix -v -full
  did not produce any messages about database state, so test DB should be restored from copy.
  Decided to change name of this test after getting reply from Roman Simakov (21-feb-2018 12:19)
  that this bug was already fixed by dimitr in:
  https://github.com/FirebirdSQL/firebird/commit/9afef198c17368276ccd7a428e159c1ca5684a60
  (Postfix for CORE-2284/CORE-5677, fixes regression CORE-5756)
NOTES:
  Script for test is launched here TWO times ("pass I", "pass II").
JIRA:        CORE-5756
FBTEST:      bugs.core_5756_addi
NOTES:
    [25.11.2023] pzotov
    Writing code requires more care since 6.0.0.150: ISQL does not allow specifying duplicate delimiters without any statements between them (two semicolon, two carets etc).
