I did modified the Fl class to allow overwrite Fl::handle and now I can
catch any non managed exception on the override Fl:handle, but I'm getting
zombie windows when an exception is caught.
---- Fl.H
...
/** signature of main event handler */
typedef int (*Fl_Main_Event_Handler)(int e, Fl_Window* w);
...
// event destinations:
static Fl_Main_Event_Handler main_handle;
static int default_main_handle(int, Fl_Window*);
static int handle(int e, Fl_Window* w) {return (*main_handle)(e, w);};
...

----Fl.cxx
...
Fl_Main_Event_Handler Fl::main_handle = &Fl::default_main_handle;
int Fl::default_main_handle(int e, Fl_Window* window) //renamed Fl::handle
to Fl::default_main_handle
