Not implemented stop reason (assuming exception): watchpoint-trigger

Using GDB 10.1, stepping and printing values works in general.

When I add a watch like the following *(char(*)[8])(0x7fd9166daa8a) I can directly see its current value and also see the value when GDB halts. But it seems to be more of a monitor as it does not stop when the variable changes. This may also be the reason

When I use the debugging console to manually add it watch *(char(*)[8])(0x7fd9166daa8a) then the program does stop as expected and also shows the old and new variant (as expected); but there is a notification and error message, which is bad.

Please catch the event and gracefully stop + update the value in the watch pane (or add it to the watch if it isn't included already).

Obviously there are more watchpoint related triggers:

  "watchpoint-trigger",
  "read-watchpoint-trigger",
  "access-watchpoint-trigger",
  "watchpoint-scope",

That should be added to the current list in the backend:
