JUCE::Timer - if (! deliverNextMessage()) - JUCE Message Thread (1): signal SIGABRT

what it could be, I can’t find out how to deal with that. I get that error in some specific situation. It’s little bit complicated to explain. But maybe anyone could give some hint. I get error in that method:

void runLoopCallback() noexcept
    for (int i = 4; --i >= 0;)
        if (! deliverNextMessage())         // ERROR "JUCE Message Thread (1): signal SIGABRT"
