AV in a bar manager's DoCreate method when this bar manager resides on TFrame placed into another TFrame that already has a Handle, but its Parent is nil

created 12 years ago (modified 12 years ago)

I am getting an AV with the call stack below after moving from 12.3 to 12.5. Are there any known issues? it is a pretty complicated section of my app and would be hard to create a demo.

    I rolled back to 12.3 and everything worked fine--then I reinstalled 12.5 and the AV problems came back.
    I have attached a madExcept bug report.
