Bug ID: 29578
Summary: Definition of SUN_LEN() is wrong
Product: glibc
Version: 2.38
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: bart.vanassche at gmail dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
$ PAGER= git grep -A1 'define SUN_LEN'
socket/sys/un.h:# define SUN_LEN(ptr) ((size_t) (((struct sockaddr_un *)
0)->sun_path) \
socket/sys/un.h- + strlen ((ptr)->sun_path))
An ampersand (&) is missing after (size_t).
The commit that introduced this incorrect definition is d38cd08ca397 ("update
