#                  Confirmed bug on: WI-V2.5.1.26351. Works fine on WI-V2.5.2.26540
#                  On 2.5.1:
#                  1) test finished with:
#                    ERROR: bugs.core_3732
#                    Test cleanup: Exception raised while dropping database.
#                    FAILED (errors=1)
#                  2) firebird.log did contain:
#                    REMOTE INTERFACE/gds__detach: Unsuccesful detach from database.
#                    Uncommitted work may have been lost
