terminate called without an active exception

[boyce-xx]

I encountered a fatal error during my test(running about 15 minutes) as below, my test app will exit when it happened, but my network is good to test, how this error happened? and how can I avoid it? and I saw this, but have no answer.

2017-08-31 12:16:16.313 [  9] E HTTP2Transport:pingFailed:responseCode=0
terminate called without an active exception
Aborted

some code snippet:

 m_stateSynchronizer = StateSynchronizer::create(
    mWisAvs.m_contextManager,
    m_messageRouter); 
ASSERT_NE(nullptr, m_stateSynchronizer);
auto stateSynchronizerObserver = std::make_shared<TestStateSynchronizerObserver>();
m_stateSynchronizer->addObserver(stateSynchronizerObserver);
mWisAvs.m_connectionManager->addConnectionStatusObserver(m_stateSynchronizer);

Hi Boyce,

Are you able to provide some steps we can use to reproduce this issue using the SampleApp or one of the unit/integration tests? Alternately, if you are using some custom code, can you provide a compilable example that demonstrates the issue? The error you are seeing indicates that a thread has been destroyed without first being joined, but we don't have enough detail in the log to tell which thread.

Other things which might help us debug:

• Turn on DEBUG9 logging and send more of the log leading up to the error
• Run the application inside a debugger and capture the backtrace when the program aborts

This error occurred in the 251th line of the HTTP2Transport.cpp file while try to join thread.(Version 1.0.2)

After connect to AVS, it seems like will try pingStream every five minutes. It will free the class of HTTP2Transport and do disconnect while pingFailed. This error will occur at that time.

Reproduction：

1. Connect to AVS;
2. Disconnect network connections.
   After about five minutes, printf the pingFailed log, this error occurred.

Thanks for the clarification @jacky-ge. I've reproduced the crash as you've described. We will investigate and and get back to you with our findings.

@kencecka Do you have a update for this issue? Or can you provide a workaround?
When we try to play iHeartRadio for long run test, we often see this occur in 2 hours, and it's a blocker for us.(it needs to play for 8+ hours for certification)
Thanks.

when the following error happened，SampleApp will also exit.

Hi NyxRockchip2017,

We have root caused the problem (HTTP2Transport's network thread ends up triggering a join on itself). We have fix in progress for the next release.

The log in your latest comment looks like a separate issue. Would you please create a new issue for that and include more comprehensive logs and steps to reproduce the problem, if possible?

Thank you!

Hi SWH, is it possible that you can provide the fix to us before your formal release? We can't wait to try this fix. :)
This issue often occurs when we're doing long run test. Thanks.

Hi @boyce-xx , did you try version 1.0.3 ?

[jacky-ge]

@mradulan I have tried version 1.0.3, the problem is not solved. Will there be any updates recently?

[mradulan]

Hi @jacky-ge , there will be an update soon. Thanks!

[kclchan]

The issue is fixed in v1.1.0. Thanks!

We have reproduced the issue that SampleApp will exit in connecting to AVS.
