Summary: Use of debugger in callbacks
Project: GNU Octave

_______________________________________________________
Details:
Debugging errors in callbacks is difficult as the call stack is not displayed
and only this error message appears:
execution error in graphics callback function
-verbatim+
as, for example, here:
function testme
F = figure ();
uicontrol (F, 'String', 'Button', 'Callback', @clbk);
endfunction
function clbk (h, e)
throw_an_error ();
endfunction
then if one use 'dbstop if error', click the button and type 'dbquit', there's
a segfault.
