No, the errors are printed in a terminal window. Since I have visual studio loaded on that machine, I get a VS pop up asking if I want to enter the debugger. I can see the stack in the debugger, but there are no symbols, etc so I'm not sure a stack trace there would be helpful. If I don't enter the debugger, the entire application immediately closes. I did create a core dump, but it's over half a gigabyte.<div> </div><div>If you can tell me what would be helpful from the VS debugger, I can try that.
