Each of the failing compiles abended in very different stages of the compile process, i.e. when compiling different modules. The errors did not always show as “segmentation fault” but also as “internal compiler error”.

After several attempts (2 to 5, depending on device) I was able to “fix” every device. The problem has been resolved so far as all my devices work for now. Nevertheless, it would be good to have an explanation for the compile errors.

What platform are you running ESPHome on?
