Bug ID: 123768
Summary: string literal warning not useful for strftime
Product: gcc
Version: 13.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: mgrant at grant dot org
Target Milestone: ---
Compiling lines like this with -Wformat=2 or -Wformat-nonliteral:
strftime(s, sizeof s, time_format, &tm);
causes this warning:
warning: format not a string literal, format string not checked
[-Wformat-nonliteral]
This warning is useful for printf/sprintf but not useful for strftime which
does not depend on its time_format to have matching % params in the arg list.
