in g++, asan fails to detect a memory leak

[mmomtchev]

I am not very sure if this belongs here or with g++, but here it is:

#include <iostream>
#include <vector>

class Object {
public:
  Object() = default;

private:
  int data;
};

int main() {
  auto *list = new std::vector<Object>;
  std::cout << list << std::endl;
  return 0;
}

Compile with

g++ -g -O0 -o test_asan -fsanitize=address,leak test_asan.cc

No leak detected

Compile with

clang++ -g -O0 -o test_asan -fsanitize=address,leak test_asan.cc

Leak detected

Tried with both g++ 11.4 and 13.2 (Ubuntu 22.04 and Ubuntu 24.04).

Reproducible with trunk GCC: https://godbolt.org/z/xebMW6qT1

I would be interested in working on this issue, however I am currently in the middle of a huge judicial scandal which involves Google, sexual elements and corruption in the French and EU justice systems. People are posting simultaneously in issues that I have been opening to intimidate me. Yours is simultaneous with swig/swig#2167 in the SWIG project. I am the author of SWIG JSE which currently cannot be merged because the SWIG project has made it clear that they had conditions linked to this criminal affair. Do you have such conditions too? Is working on this project subject to agreeing to corruption in the justice system?

This is a forum for technical discussions. Please abstain from accusations and topics that do not directly relate to sanitizers.

Well, don't post messages directly related to these affairs in this case.
