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.

Avrdude is the workhorse for programming AVR chips from Atmel (now Microchip). It works flawlessly on all platforms with a huge number of different programmers. There are a few exceptions, though. The Atmel-ICE, a very decent programmer and debugger, could not be used under macOS (>10.13). But finally there seems to be light …
