Details

Description:
When upgrading to the current version 232 (revision 1 to 3) of systemd. The PID1 will crash during update, when one or more partition names in /dev/disk/by-partlabel contains invalid characters. The systemctl command cannot be run anymore. The system will not be able to boot again until downgraded to version 231 (any revision)


Additional info:
+ Works fine until systemd-231-4
- Broken since systemd-232-1 until systemd-232-3

Steps to reproduce:
Name a NTFS partition "†††††††††††††††††††††††††††††††††††"

$ blkid |grep sda6
/dev/sda6: LABEL="Work" UUID="E63E05143E04E003" TYPE="ntfs" PARTLABEL="M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- M-bM-^@M- " PARTUUID="6b316bcc-450c-11e5-985b-806e6f6e6963"

I can't see how this could be a packaging issue. You'll want to take it upstream.

You'll need to provide the assertion failure at minimum, but ideally a backtrace from the abort. I can't reproduce this with the info given... my guess is there's invalid utf8 somewhere in that PARTLABEL.

Okay... managed to reproduce this. Should be easy enough to bisect.
