Bug ID: 98992
Summary: attribute malloc error associating a member
deallocator with an allocator
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: msebor at gcc dot gnu.org
Target Milestone: ---
The new attribute malloc is rejected on declarations of member function:
$ cat t.C && /build/gcc-master/gcc/xg++ -B /build/gcc-master/gcc -S -Wall t.C
struct A
{
void dealloc (void*);
__attribute__ ((malloc (dealloc)))
void* alloc ();
};
t.C:6:16: error: ‘malloc’ attribute argument 1 does not name a function
6 | void* alloc ();
| ^
The attribute handler is prepared for FUNCTION_DECL and OVERLOAD but not for
how a member function is represented here:
