Here is a big problem: The error occurred during a QSO on the air.

In the mentioned situation, I'm not able to give you many information. I was performing QSOs on the air, as usual. Of course, the system is always changing a little bit because of system updates. Really, I have only few information. Perhaps just the following one: The waterfall window was frozen. I have terminated wsjtx with the exit button, as usual. All windows have then be closed but a wsjtx process was still running. My idea was to try to locate which processes are running, which ones are dead, where the instruction pointer is, in every process, what is in the stack, etc. My idea was to give you this information. Because of the multiple processes, it is probably not easy to find this information using gdb. I'm not sure if Qt-creator can help here. It includes a debugging support. I have no skill using Qt5.
