     // needs more than one thread
     std::thread t{ [&]{ ios.run(); } };

     ios.run();
     t.join();

     return 0;
 }

 Prints:
 {{{
 [1]
 [2]
 }}}

 and crashes.

 Debugger points to `_FindAndUnlinkFrame` (inside `trnsctrl.cpp` file):
 `pCurFrameInfo->pNext` causes AV because pCurFrameInfo is null.
