# title:        Regression: FB crashes when trying to recreate table that is in use by DML
# decription:   
#                   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 .fbt 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)
#                   Checked on:
#                       3.0.4.32920: OK, 2.625s.
#                       4.0.0.912: OK, 2.781s.
#                   ::: NOTE :::
#                   Script for test is launched here TWO times ("pass I", "pass II").
