Bug ID: 81777
Summary: Compiler doesn't detect wrong function declaration
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: jsiebert at poczta dot wp.pl
Target Milestone: ---
Is it possible to miss wrong declaration of function in seperate include file.
An example:
file testarg.c:
#include <stdio.h>
typedef struct {
int c;
} test_t;
void testarg(test_t *t)
{
printf("c = %d\n", t->c);
return;
}
file testarg.h:
void testarg(void);
file test.c:
#include "testarg.h"
int main(void)
{
gcc test.c testarg.c -o test
testarg();
return 0;
}
compilation with:
gcc -Wall -Werror -pedantic-errors test.c testarg.c -o test
gives no warning or error about wrong testarg() usage.
