Bug report: TSqlMonitor.Active= true => exit() fails

Post by albourgz » Fri 24 Apr 2020 12:04

using unidac 8.1.2 on c++ builder 10.3.2.
New project, vcl win32.
Drop a TuniConnection, set database to oracle, no need to connect it.
drop a TOracleUniProvider and a TUniSQLMonitor1

in the form's constructor, type

Run the program. The exit will not work.
Uncheck the SQLMonitor.Active. Build program. It works.

So when there is a SQLMonitor component, activated, it prevents the program to exit normally, with an exception:
Debugger Exception Notification
Project Project112.exe raised exception class $C0000005 with message 'access violation at 0x77373cb3: write of address 0x00000014'.
Break Continue Help

The exception happens always, no matter if the connection is active or not.
