Hey guys, we are currently facing an avr-gcc/avr-libc problem in Archlinux. With avr-gcc 6.x we got the problem that cxa_aexit seems to cause issues with lto if its disabled. We cannot enable it, as its not defined in avr-libc.
We've got some workarounds, but I hope someone can help use find the real issue and possibly also solve it. You may have a look at it more detailed here: https://bugs.archlinux.org/task/50848 Cheers, Nico
