I'm seeing a weir behavior with sys-apps/acl-2.2.53. With 2.2.52-r1, reading and setting acl on a file works as expected: > touch 52 > getfacl 52 # file: 52 # owner: cova # group: cova user::rw- group::r-- other::r-- > setfacl -m g:cova:rwx 52 > getfacl 52 # file: 52 # owner: cova # group: cova user::rw- group::r-- group:cova:rwx mask::rwx other::r-- However, this changes with 2.2.53: > touch 53 > getfacl 53 # file: 53 # owner: cova # group: cova other::r-- > setfacl -m g:cova:rwx 53 setfacl: 53: Malformed access ACL `group:cova:rwx,mask::rwx,other::r--': Missing or wrong entry at entry 1 > getfacl 53 # file: 53 # owner: cova # group: cova other::r-- The system is the same, I've only emerged 2.2.53 and tested again. This causes various side effects, one being udev unable to enforce uaccess param.

The issue is related to LTO flag for compilation. Removing LTO will make the issue to disappear. I informed upstream about this finding.
