systemd-systemctl-native broken after update to walnascar #poky #yocto

Hi,

when we upgrade poky to walnascar, our builds fail due to systemd-systemctl-native (please find the log attached).

As a workaround we disabled Werror-nonnull with a simple .bbappend:
BUILD_CFLAGS += "-Wno-error=nonnull"

We managed to narrow down the issue to our use of DEBUG_BUILD=1 in local.conf. Images can be built again when we remove it. However, we struggle to solve this issue on our own. Is it possible for anyone to reproduce this issue? Adding DEBUG_BUILD=1 to local.conf should be enough, then bitbake systemd-systemctl-native should fail.

Greetings,
Jan
