Description
After upgrading to the latest qt creator version using MaintenanceTool, I am having all sort of issues when trying to debug. I am not sure what version of qt-creator I had installed before the upgrade, but it was at least whichever did come with Qt 5.12.x. At some point, I did upgrade from 5.12.x to 5.14.1 and then to 4.14.2 when it was available. Again very recently (week or little more I upgraded to 5.15.2 qt creator with maintenance tool)
Before I get to the current issue, I like to mention a related issue? that I never reported. I noticed that with the previous qt creator, whenever I started debugging and I placed breakpoint at the end of the source file, right after debugger started, execution stopped at the very end line of the source file. I had to press continue and everything was fine. It little annoying but I could live with it.
Now in the current version after an upgrade, I place breakpoints at various places in my source file. Then I start debugger some breakpoints are switched few lines down and some disappear from the left side of the editor window where you see line numbers.
While debugging I try to add a breakpoint by clicking on a valid line on left side of the editor (it is always how I enable disable breakpoints, except clearing all in "breakpoint watch window"), In some cases breakpoint is inserted few lines below and not where I want it.
