| Build successful but loading fails |

I've had a bug show up once that I never posted here before, but I figured out how to reproduce it today and I wanted to share.
I'm using CCS v5.085, MPLABx v5.15.
What happens is that when you try to build or download code, building succeeds, but loading fails with this message in the output:
| Code: | | The program file could not be loaded: Index: 0, Size: 0 |
EDIT: fixed image to be more specific
This shows up when I tick this box in project properties:
So if you are having this problem, one thing to try is to make sure this box are not ticked.

I have to ask 'why' you would be ticking the second?.
You do realise that if this is ticked, it expects you to put the name of the
file it is to load in the window underneath. If there is no name there, it'll
load nothing.... |

Sloppy on my part... I never tested them in isolation.
It is the first box that is the deal breaker here. If you tick the second box, it unticks itself if you don't put anything in the text box. I'll edit the picture to reflect this. |

| Are you building for DEBUG or release?. |

I have only been using build for release.
I just found out that building for DEBUG gives that error message whether or not I tick the box.
In both cases when there is a failure, I think it fails in loading the .cof file somehow, since that is what it's doing right before it fails.
Anyway, the reason that I wanted to load symbols in the first place was to see the data and program memory usage in the IDE. I can always see memory usage in the .lst file, but this seeing it in the IDE was more convenient. |

The symbols should always load automatically when debug is selected. This
option only 'turns it on' when debug is not selected.
Suggests that for some reason MPLAB is not correctly interpreting
the symbol file. |
