title: Qt +musl system exception
body: <p>Hi I build library in c++ and program in c++ that open dll, and it works. Problem is that when I want to open my dll using qt it's open it load symbols but after that when I want to use it and call some function I've got system exception.
  I read that mixing libgcc_s.so.1 maybe the problem, but I don't know what is the cause.</p>
