Bug ID: 95759
Summary: Sized deallocation function can not be matched
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: hujiangping at cn dot fujitsu.com
Target Milestone: ---
Accroding to https://gcc.gnu.org/projects/cxx-status.html#cxx14, sized
dealloction function which is one of C++14 language features should have been
implemented from GCC 5. But, I cann't get the following replaced one matched.
---
#include <cstdlib>
#include <cassert>
#include <stdio.h>
void* operator new[](std::size_t sz){
printf("new called\n");
void* m = malloc(sz);
assert(m);
return m;
}
void operator delete[](void*p)noexcept {
printf("usual deallocation called\n");
return free(p);
}
void operator delete[](void*p, std::size_t size)noexcept {
printf("sized deallocation called\n");
return free(p);
}
void test() {
delete[] new int[3];
}
int main() {
test();
}
---
The gcc version and command used are as follow:
---
$ /home/extra_mnt/build_gcc/bin_gcc-master/bin/g++ --version
g++ (GCC) 11.0.0 20200519 (experimental)
Copyright (C) 2020 Free Software Foundation, Inc.

$ /home/extra_mnt/build_gcc/bin_gcc-master/bin/g++ --std=c++14 tmp.cpp &&
./a.out
new called
usual deallocation called
---
I guess if the sized deallocation funtion may not replaceable, or there is a
mis-matched bug?
