Bug ID: 18280
Summary: -Wformat does not warn for inlined functions
Product: clang
Version: 3.0
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
When I give an inlined definition to a function, the warning about "non-literal
format string" goes away.
For example:
---
#include <stdarg.h>
#include <stdio.h>
const char* dummy();
class Test1 {
public:
Test1(const char* fmt, ...) __attribute__((format(printf,2,3)));
};
class Test2 {
public:
Test2(const char* fmt, ...) __attribute__((format(printf,2,3)))
{ va_list a; va_start(a, fmt); vprintf(fmt, a); va_end(a); }
};
void tester() {
Test1 t1(dummy());
Test2 t2(dummy());
}
---
This compiles with no warning for t2 on clang ("clang++ -c test.cpp"), but
produces warnings for both cases using GCC ("g++ -c test.cpp").
