# title:        Engine crashes when trace config contains line "connection_id=NN" and we attempt to connect to non-existent database/alias
# decription:   
#                  Test receives version of FB (2.5 or 3.0) and prepares text file that will serve as TRACE config.
#                  This text file will contain trivial content appropriate to FB version with 'connection_id=NNN' key.
#               
#                  Than we make async start of trace session using FBTRACEMGR utility and after small pause (~1 sec)
#                  run ISQL with attempt to make connect to non-existent alias.
#               
#                  Confirmed crash on WI-T3.0.0.30566 (Alpha 1). Note: utility fbsvcmgr can not start when trace config 
#                  contains connection_id: standard Windows crash report appears with such data:
