Crash when using std::thread to execute lambda function using Visual Studio 2015

I have this function, try to ignore the types of parameters and variables. I'm absolutely sure that the objects are still there (they are created on the same thread before calling this function).

void ClientLoadUnloadStressTestcase::RunMasterForScenarioOverTimeWithAllConnections(ConnectionsController* Controller, MasterIPC &MasterIpc){

// Signal clients that we are set-up
MasterIpc.SignalAllClients();

ComputeEndTimeForScenarioOverTime();

std::atomic_bool mustContinue = true;

std::thread t{ [&]() {
    while (mustContinue)
        RunNewConnectionsSet(Controller, m_connectionNumber, m_dataSize);
} };

// Wait for time to be elapsed and clients to finish filtering.
MasterIpc.WaitForAllClients(TIME_TO_WAIT_FOR_TESTCASE_PROCESSES_TO_FINISH);

mustContinue = false;
t.join();

// Signal clients that connections are finished
MasterIpc.SignalAllClients();
}

Now, the problem is that once in a while, on some builds, the generated program will crash on the newly created thread, right here:

std::thread t{ [&]() {
while (mustContinue)
    RunNewConnectionsSet(Controller, m_connectionNumber, m_dataSize);
} };

This is the callstack when the crash happened (I stripped out the arguments and other unnecessary information):

That address that you see on the stack 0x00000001'43a25f50 is actually the address of the MyObject (this) that is passed to the lambda function (because it is using it to run MyObject::RunNewConnectionsSet method).

This crash happens only on some builds, but the executable will always crash on that line. We had the issue from thread several times before, but now I really wanna find an answer. Please help :).
