[Bug preprocessor/60975] -Wvariadic-macros does not print warning
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60975 --- Comment #2 from Prathamesh --- Hi, Consider the following test-case: #define FOO(a...) When compiled with: gcc -E -Wpedantic the following warning gets printed: empty-arg.c:1:14: warning: ISO C does not permit named variadic macros [-Wvariadic-macros] #define FOO(a...) ^ However If I only pass -Wvariadic-macros, the warning is not printed. For example: gcc -E -Wvariadic-macros and neither does gcc -E -Wvariadic-macros -std=c90 Is that intended ? Tested on gcc-4.8.2 gcc -v: Using built-in specs.

[Bug c++/61018] New: -Wvarargs does not print warning for memer functions
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=61018
Bug ID: 61018
Summary: -Wvarargs does not print warning for memer functions
Product: gcc
Version: 4.8.2
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: bilbotheelffriend at gmail dot com
Hi,
It appears to me that, g++ does not warn for -Wvarargs for member
functions.
For the following test-case:
#include
struct f
{
void foo(int x, int y, ...)
{
va_list ap;
va_start (ap, x);
}
};
I compiled it with g++ -Wvarargs, and it only printed the warning:
wa.cpp:4:6: warning: unused parameter ‘y’ [-Wunused-parameter]
void foo(int x, int y, ...)
Test-case for non-member function:
#include
void foo(int x, int y, ...)
{
va_list ap;
va_start (ap, x);
}
Compiling with g++ -Wvarargs additionally prints:
foo.cpp: In function ‘void foo(int, int, ...)’:
foo.cpp:6:19: warning: second parameter of ‘va_start’ not last
named argument [-Wvarargs]
va_start (ap, x);
g++ -v:
Using built-in specs.
