Unfortunately this is triggering by the libselinux library constructor when it tries to read /proc/mounts to find out if selinuxfs is mounted in an unusual place. This, however, only affects libselinux in Debian as that opens with "r", while in Fedora / RHEL it opens "re" and thus luckily never triggered the abort(), instead getting an EACCESS.
