All of a sudden, my Delphi 10.3 stopped showing compiler hints in some (but not all) procedures of one project (but not others - and may I add that I have far more complex ones). MadDebug stopped working with this error:
[madExcept Warning] Mapping binary file failed (1)
Enforcing hints with $ and un/re-installing MadCollection doesn't help.
Obviously (just another one of many) bug(s) in the delphi environment. The problem disappeared when I changed the platform from 32-bit to 64-bit Windows (so I do the development on 64-bit and finalize on 32-bit).
