Segfault in release build

[eugene345]

Hello,

I'm on Ubuntu 15.04 now. I have a segmentation fault for release build only. Debug build works fine. The library was compiled with STATIC_LINKING=1. Compiler - GCC 4.9.2.

My code:

bool MainWindow::credentialsProviderTest()
{
    Aws::Utils::Logging::InitializeAWSLogging(Aws::MakeShared<Aws::Utils::Logging::DefaultLogSystem>(ALLOCATION_TAG, Aws::Utils::Logging::LogLevel::Trace, "aws_sdk_"));

    // Create a client
    ClientConfiguration config;
    config.scheme = Scheme::HTTPS;
    config.connectTimeoutMs = 30000;
    config.requestTimeoutMs = 30000;

    auto cognitoIdentityClient = Aws::MakeShared<CognitoIdentityClient>(ALLOCATION_TAG, Aws::MakeShared<SimpleAWSCredentialsProvider>(ALLOCATION_TAG, "", ""), config);
    auto cognitoCachingAnonymousCredentialsProvider = Aws::MakeUnique<CognitoCachingAnonymousCredentialsProvider>(ALLOCATION_TAG, accountId, identityPoolId, cognitoIdentityClient);
    AWSCredentials credentials = cognitoCachingAnonymousCredentialsProvider->GetAWSCredentials();
    credentials = cognitoCachingAnonymousCredentialsProvider->GetAWSCredentials();

    Aws::Utils::Logging::ShutdownAWSLogging();
    return true;
}

Stack trace:

runCognitoIntegrationTests shows same problem:

log

I don't think the log is for this code: It makes a ListIdentityPools, and does so unsigned (which will fail).

Anyways, we had a bug a long time ago (on linux) where a string going out of scope in the curl client was causing a segfault in the makeRequest function. Any chance you could dig down into that? For starters what curl version are you using?

[eugene345]

Sorry, yes, this log file is for runCognitoIntegrationTests. Logs for my code below:
release
debug

Curl version:
curl 7.38.0 (x86_64-pc-linux-gnu) libcurl/7.38.0 OpenSSL/1.0.1f zlib/1.2.8 libidn/1.28 librtmp/2.3

I have no idea, how to debug makeRequest, since release build hasn't symbolic debug information. Can you help me, please?

[JonathanHenson]

Good point. I'll try and see if I can reproduce the problem today.

This is definitely that old bug we had with curl. Can you run:

valgrind --tool=memcheck and upload the result?

[eugene345]

valgrind --tool=memcheck

[JonathanHenson]

ok, one more experiment (I haven't been able to replicate the issue yet). In Aws::Http::CurlHandleContainer() class
Aws::Auth::CognitoCachingCredentialsProvider::GetCredentials() methods
Aws::Client::AWSClient::AddContentBodyToRequest() method
Aws::Client::AWSClient::AttemptOneRequest() method
Aws::Http::CurlHttpClient::MakeRequest()

could you change the log statements to use the LOGSTREAM api, recompile and try again. That is the only suspicious thing I see in the valgrind output and I'm curious if something is overwriting memory somewhere and we just can't see it until release build time.

[eugene345]

Can you explain, please, what is difference between these apis?

[JonathanHenson]

Yeah, log uses sprintf under the hood with va_args and the other uses std c++ steams. I'm curious if something bad is happening under the hood with the va_args stuff and I'd like to rule that out.

[JonathanHenson]

notice in AWSClient.cpp

AWS_LOGSTREAM_TRACE(LOG_TAG, "Error response is " << exceptionPayload.WriteReadable());

as opposed to
AWS_LOG_TRACE(LOG_TAG, "Error response is %s", exceptionPayload.WriteReadable().c_str());

[eugene345]

can I just disable logging in my code to check it?

[JonathanHenson]

ah! yes you can. Good call.

[eugene345]

I've tried already, but the problem still exists.

[JonathanHenson]

hmmmm..... With logging turned off, can I see your valgrind output? That may actually make the issue more obvious.

I tried to compile it, but got few errors:

I commented lines in CurlHttpClient which caused errors and compiled successfully. Now release build on linux works fine and there is no segfault error.

Sorry, there is a merge in there for some new features I forgot about.

Did you mean release build works with no errors? Or have you not tried that
yet?

Sorry, yes, I mean release build works fine.

[JonathanHenson]

Ok, I fixed a bunch of suspicious things in there. Could you check size of
int and size of long on your system?

int - 4 bytes
long - 8 bytes

[JonathanHenson]

That was it. Cool. We've got another build coming out today and it will
contain the fix for you. Sorry for the inconvenience and thank you for your
patience.

Thank you too!

[JonathanHenson]

fix has been pushed. If you have time could you confirm everything works for you now and then close the issue if it has been fixed?

[eugene345]

Yes, the bug is fixed now.
