Subject: [Bug c++/108231] malloc attribute vs extern "C" in a namespace and global and using of one in the namespace in the global one
Date: Tue, 27 Dec 2022 07:45:01 +0000	[thread overview]
Message-ID: <bug-108231-4-XSeGbRoWP2@http.gcc.gnu.org/bugzilla/> (raw)

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
A little more reduced:
```
namespace g {
extern "C" void free(void *);
}
using g::free;
extern "C" void free (void *);

void foo1 (void *p) { free (p); }
void (*foo2) (void *) = free;
extern "C" {
void foo3 (void *p) { free (p); }
void (*foo4) (void *) = free;
}

extern "C" wchar_t * wcsdup (const wchar_t *s) 
__attribute__ ((__malloc__)) __attribute__ ((__malloc__ (free, 1)));
```
