--- Comment #1 from R. Diez <rdiezmail-gcc at yahoo dot de> ---
I have been using the following up to GCC 11.3:
struct MyClass
{
static void FreeMemory ( const void * pMem ) throw();
#if __GNUC_PREREQ(11, 0)
__attribute__ (( malloc, malloc( MyClass::FreeMemory, 1 ) ))
#else
__attribute__ (( malloc ))
#endif
static void * AllocMemory ( size_t Size ) throw();
[...]
};
However, GCC 12.1 does not want to accept it anymore:
error: 'malloc' attribute argument 1 does not name a function
I tried placing the attribute outside the class, like this:
__attribute__ (( malloc, malloc( MyClass::FreeMemory, 1 ) ))
void * MyClass::AllocMemory ( size_t Size ) throw()
{
return malloc( Size );
}
But then I got 2 errors:
error: 'static void MyClass::FreeMemory(const void*)' is protected within this
context
710 | __attribute__ (( malloc, malloc( MyClass::FreeMemory, 1 ) ))
| ^~~~~~~~~~
error: 'malloc' attribute argument 1 does not name a function
That cannot be right. GCC should not insist that the deallocator is public.
After all, the allocator AllocMemory is not public.
