# title:        Trace config with misplaced "{" lead firebird to crash
# decription:
#                 We create trace config with following INVALID content:
#                   database = (%[\\/](security[[:digit:]]).fdb|(security.db))
#                   enabled = false
#                   {
#                   }
#
#                   database =
#                   {
#                     enabled = true
#                     log_connections = true
#                   }
#
#                 Then we run new process with ISQL with connect to test DB.
#                 This immediately should cause raise error in the 1st (trace) process:
#                     1  Trace session ID 1 started
#                     2  Error creating trace session for database "C:\\MIX\\FIREBIRD\\FB30\\SECURITY3.FDB":
#                     3  error while parsing trace configuration
#                     4  Trace parameters are not present
#                 NOTE.
#                 It was encountered that in FB 3.0.3 Classic lines 2..4 appear TWICE. See note in the ticket, 16/Jan/18 05:08 PM
