What version of protobuf and what language are you using?
Version: 4.25.0 (archlinux protobuf version 25.0-1) (absl version 20230802.1-1)
Language: C++

What operating system (Linux, Windows, ...) and version?

Linux (arch 6.6.1-arch1-1)

What runtime / compiler are you using (e.g., python version or gcc version)

gcc 13.2.1 20230801
clang 16.0.6

What did you do?
Steps to reproduce the behavior:
Example proto:

syntax = "proto3";

message Test {
 int32 number = 1;
}

Example code:

#include <google/protobuf/message_lite.h>
#include <iostream>
#include "test.pb.h"

int main(){
    GOOGLE_PROTOBUF_VERIFY_VERSION;
    {
        Test test;
        test.set_number(1);
        std::cout << "Test: " << test.DebugString() <<  std::endl;
    }
    google::protobuf::ShutdownProtobufLibrary();
    return 0;
}
valgrind --leak-check=full ./test

What did you expect to see

No leak as with versions <=4.24

What did you see instead?

Anything else we should know about your project / environment

ASAN does not indicate anything, so this might be an valgrind thing. Also happens if google::protobuf::util::MessageToJsonString is called.

FWIW this is a fixed-size global that doesn't represent any kind of dangerous leak, but I'll added a deleter to clean it up

I have just updated protobuf to 4.24.4 (C++) (and abseil to 20230802.1) and I now see several Valgrind issues that I have not seen with the version we used before (protobuf 3.19.2 without abseil).
I have also tried protobuf 4.25.2 where the shutdown deleter is added, but I still get the same Valgrind issues reported:

Is this related in any way? Do I have to do some clean up? google::protobuf::ShutdownProtobufLibrary(); seems to not help.

Context:
We are using protobuf with grpc. There were no leaks reported with grpc 1.39.1, protobuf 3.19.2.
Now with grpc 1.59.3 and protobuf 24.4 / 25.2 these leaks are reported.

Since this is some static initialization/allocation done before the program really starts I guess it is save to suppress it, right? But I would be more relaxed if I could get rid of these Valgrind issues :)
