<![CDATA[Why is GDB "terminating"?]]>I am trying to test / debug "viewportMargins" , and it runs OK , but "GDB" terminates in debug. Why?

Actually I need to "get" current viewport margins and I am not sure at what point (of constructor code ?) I can do that.

If this persists, you can also use LLDB. This will not be uniformly better, but possibly not crash in this exact location.

It is known that Ubuntu 22.04 is shipping a "beta" version of gdb (12.0.90) which has problems, and the fix is to upgrade to gdb version 12.1.0.
