Hi, I'm running LFS (Linux From Scratch) and yesterday I upgraded glibc to 2.24 (up from 2.23) and more significantly, glib to 2.49.4 (up from 2.49.2). glib-networking is 2.48.2, if it matters. lighdm is 1.19.3 using the gtk-greeter 2.0.1. glibc 2.23 + glib 2.49.2 + lightdm 1.19.3 + lightdm-gtk-greeter 2.0.1 worked just fine. glibc 2.24 + glib 2.49.4 + lightdm 1.19.3 + lightdm-gtk-greeter 2.0.1 doesn't work, when started as a systemd service. This is the error from the journal: [root at tervel (x86_64) ~]$ systemctl status lightdm● lightdm.service - Light Display Manager Loaded: loaded (/lib/systemd/system/lightdm.service; enabled; vendor preset: enabled) Active: failed (Result: start-limit-hit) since Sat 2016-08-06 20:03:01 EEST; 2h 41min ago Docs: man:lightdm(1) Process: 3079 ExecStart=/usr/bin/lightdm (code=dumped, signal=SEGV) Main PID: 3079 (code=dumped, signal=SEGV) Aug 06 20:03:01 tervel systemd[1]: lightdm.service: Unit entered failed state.Aug 06 20:03:01 tervel systemd[1]: lightdm.service: Failed with result 'core-dump'.Aug 06 20:03:01 tervel systemd-coredump[3087]: Process 3079 (lightdm) of user 0 dumped core.

I'm guessing it's glib that's causing the error. However, the interesting thing is, that if I just run /usr/bin/lightdm, it works without that error. Any idea?
