Hi,
I wanted to create a user account for GCC bugzilla in order to file a bug.
In case you have a place for such report, a summary is here :
The diagnostic -Wmaybe-uninitialized does not print the offending line
if the offending code happens inside a function-like macro
GCC 7.0 snapshot 7.0.1 20170305 (experimental)
macros.h:
#define print_int(x) print_it("%d",(x))
code.c:
#include "macros.h"
extern void print_it(const char *fmt, int i);
void test(void)
{
int unint;
print_int(uninit);
}
gcc -c -Wall test.c
In file included from test.c:1:0:
test.c: In function 'test':
macros.h:1:22: warning: 'uninit' is used uninitialized in this function
[-Wuninitialized]
#define print_int(x) print_it("%d",(x))
^~~~~~~~
test.c:7:7: note: 'uninit' was declared here
int uninit;
^~~~~~
so the offending line print_int() is not shown.
Regards,
Joris Wu
