Bug ID: 99291 Summary: maybe_warn_pass_by_reference uses outdated format string Product: gcc Version: 11.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c Assignee: unassigned at gcc dot gnu.org Reporter: roland.illig at gmx dot de Target Milestone: --- tree-ssa-uninit.c says: > inform (loc, "in a call to %qD declared with " > "attribute %<%s%> here", fndecl, access_str); This format string uses the sequence %<%s%>, for which there is the shortcut %qs. Using the %<%s%> should be detected and prevented by check_plain in c-format.c. Is that check not active by default?
