I still have not figured out the circumstances, but ever since either the Unicode Delphi versions (2009 and up) or BDS (8 and up), I have this every now and then: [WayBack] Delphi: why breakpoints from time to time are not usable (green highlighted line on IDE)? – Stack Overflow

So far this is consistent, limiting it to:

  • large projects (100+ kilo-lines-of-code)
  • for those projects, either as single .dproj file or as part of a .groupproj
  • debugging works the first time, but fails consistently with these symptoms:
    • break-points fail
    • blue dots in the gutter disappear; red-dots become green
    • exceptions cause a stack-trace with only hex-addresses
  • other projects in the same project group still debug fine

To get it working (one time per try) again:

  • restart the IDE
  • close the project, then re-open it in the same IDE instance

What does not help getting it to work:

  • clean build from the IDE
  • deleting DCU files
