Delphi has stopping on break points and exceptions

[PiedSoftware 5]

Hi

I have a break point, but when I run the procedure it is in the code is going right past it and putting up a message a few lines down. 
 

Also, I had a bug where the code was throwing an exception, the exception dialog would come up, but the debugger didn't stop at the relevant line.

I have been googling and poking around in the settings but nothing has shown up that would make it stop at the line. I have deleted and recreated the break point, rebooted my machine, and it looks as if Delphi is broken, but I hope not!

 

This is Delphi 10.4, building for windows32.

Try clicking Debug in Project manager, first.  

 

 

Be sure the compiled lines have blue dot in left gutter.

You may be able to click on lines in the call stack in in debug layout. This backs up the procedure calls in the code window.

Thanks for the ideas. I looked and it is in debug mode, and the lines do have the blue dots. It must be something else.

I had a look at the list of breakpoints (View | Debug windows | Breakpoint) and I had accumulated a couple of dozen, a number from files that have been removed from the project. I deleted all of them, and put back in the one that I wanted. And now it is great to see my program stopping on the line I have asked it to stop on.

Check line endings in source files. IDE often gets crazy if they're not CRLF

I've seen it happen as well. Sometimes doing a clean build and clearing/resetting the breakpoints will sort the issue out.

I did clean builds a number of times, and it didn't clear the problem. What made the difference was clearing all the breakpoints, one after the other, the putting back in the one I wanted to use.

It's happening again. There must be some other cause. I tried another smaller project. The breakpoints worked a few times and then stopped.

More checks

The provenance (path) of used units found in hint box showing when mousing over tabs over unit tabs in code window or control tabs on the component bar.    

 

Then the transactions in .proj.local can be looked at.  These transactions log when units renamed or who knows. 

 

Try syntax check or build all from time to time can't hurt!

I see the correct file names in the popup hint over the tabs for each unit.
If the syntax was wrong it wouldn't even build and run. I am doing Build fairly frequently.

I am using 11.3 a big improvement over 10.4 until the blue moon last month. Then the IDE began doing disappearing act like 10.3, after "upgrading" an event in a control in a package. In short recompiling my package of custom controls fixed the issue(s).  Looking at the output messages after a compile I may shut down the OneDrive business if the IDE crashes while hovering over the Search menu again.

Thanks. I would hope I can fix the issue with something less drastic than reinstalling. What advantages do you have with 11.3?

I think I may have solved the problem. 
Somehow the normal run button got replaced with the Run without debugging button. So far the best explanation is that when I had the problem was when I ran the program by hitting the Run button, and when it ran fine it was because I hit F9. I don't remember changing it, and I don't remember whether I hit F9 or the button each time I had breakpoints or not, But, now I am back in happy land.
