<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I tracked down the root cause of that. In unmount(), m_proc is set to nullptr before the process is killed. And Stderr/StdoutReadReady is triggered after that. So in the signal handler there's a nullptr dereference.</p>
