Crash when placing call

[pwinckles]

Describe the bug

I am using the Java pjsua2 bindings. I noticed when I built off head that the application segfaults when I place a call. This crash does not happen on 2.13.1 or 2.14.1. I did a bisect and identified that the crash was introduced by this commit: aa56436

The setup is two accounts registered to a PBX and one of the accounts attempts to place a call to the other.

Steps to reproduce

import org.pjsip.pjsua2.*;

import java.util.concurrent.TimeUnit;

public class Sample {

    static {
        pjsua2JNI.class.getName();
    }

    private static class TestAccount extends Account {

        private final String uri;
        private final String user;
        private final String password;
        private final String registrarUri;

        private TestAccount(String uri, String user, String password, String registrarUri) {
            this.uri = uri;
            this.user = user;
            this.password = password;
            this.registrarUri = registrarUri;
        }

        void create() throws Exception {
            var pjsipConfig = new AccountConfig();
            pjsipConfig.setIdUri(uri);
            pjsipConfig.getRegConfig().setRegistrarUri(registrarUri);
            pjsipConfig
                    .getSipConfig()
                    .getAuthCreds()
                    .add(new AuthCredInfo("digest", "*", user, 0, password));
            create(pjsipConfig);
        }
    }

    private static class TestCall extends Call {
        public TestCall(Account acc) {
            super(acc);
        }
    }

    public static void main(String[] args) throws Exception {
        var host = "";
        var registrarUri = "sip:%s:5160;transport=tcp".formatted(host);
        var usr1 = "";
        var pwd1 = "";
        var usr2 = "";
        var pwd2 = "";

        var ep = createEndpoint();

        try {
            var acc1 = new TestAccount("sip:101@%s:5160".formatted(host), usr1, pwd1, registrarUri);
            var acc2 = new TestAccount("sip:102@%s:5160".formatted(host), usr2, pwd2, registrarUri);

            acc1.create();
            acc2.create();

            var call = new TestCall(acc1);
            call.makeCall("sip:102@%s:5160;transport=tcp".formatted(host), new CallOpParam());

            TimeUnit.SECONDS.sleep(30);

            call.delete();
            acc1.delete();
            acc2.delete();
        } finally {
            try {
                ep.libDestroy();
                ep.delete();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }

    private static Endpoint createEndpoint() {
        var ep = new Endpoint();
        try {
            ep.libCreate();
            var epConfig = new EpConfig();
            epConfig.getLogConfig().setLevel(6);
            epConfig.getLogConfig().setConsoleLevel(6);
            epConfig.getUaConfig().setUserAgent("Test/1.0");
            ep.libInit(epConfig);

            var transportConfig = new TransportConfig();
            transportConfig.setPort(5060);
            ep.transportCreate(pjsip_transport_type_e.PJSIP_TRANSPORT_TCP, transportConfig);

            ep.libStart();
        } catch (Exception e) {
            e.printStackTrace();
            try {
                ep.libDestroy();
                ep.delete();
            } catch (Exception e2) {
                e2.printStackTrace();
            }
        }
        return ep;
    }

[sauwming]

It should have been fixed in #4073, no? (Yes, sorry, it should be #4056)

[pwinckles]

@sauwming I assume you mean #4056? If so, then no. The crash still happens on head.
