Bug ID: 95312
Summary: Missing quoting of format directives emitted by
-Wformat
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Keywords: diagnostic
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: asolokha at gmx dot com
Target Milestone: ---
All gcc since 4.6, where -Wformat was initially introduced, emit the following
when compiling snippets like that w/ -Wformat:
#include <stdio.h>
int
foo (FILE *f, char *s)
{
return fscanf (f, "%c%[^\n\n]", s);
}
% gcc-11.0.0 -fsyntax-only -Wformat -c po6k6b4n.c
po6k6b4n.c: In function 'foo':
po6k6b4n.c:6:29: warning: format '%[^
' expects a matching 'char *' argument [-Wformat=]
6 | return fscanf (f, "%c%[^\n\n]", s);
| ~~~~~^~
| |
| char *
It seems wrong to me that the format directive is not quoted in the warning
text.
