Link-time optimization (LTO) is a very powerful compiler-optimization technique. As I noticed, it does not go very well together with debugging object-oriented programs under GCC, at least for AVR MCUs. I noticed that in the context of debugging an Arduino program, and it took me quite a while to figure out that LTO is the culprit.

One has to add to the title (quoted from a tweet by Filipe Fortes) that the detective suffers from memory loss. Otherwise, the case could be solved easily. Similarly, with debugging: If I only knew what nasty things I have hidden in the source code, I could just remove them – but I simply do not know. In this blog post, we will have a look at what kind of tools one could use to find the skeletons hidden in the closet.
