Personally, I find DEBUG conditional compilation a bad idea:
- Needs recompilation to switch from debugging to regular mode or back
- That recompilation often changes behaviour (so that bugs are hidden or act differently)
- DEBUG code is rarely compiled and easily becomes dysfunctional without being noticed (like in this case)
However, code should compile with -DDEBUG set.
Two options: fix or remove. Should that be discussed at the upcoming
Core meeting?
