Ok, here is the exact situation:


void 
main_prog(int argc, char* argv[])
{
  [..]
  gtk_main();
  g_print("Do we quit gtk_main?\n");
}

int main(int argc, char* argv[])
{
        gh_enter(argc, argv, main_prog);
        g_print ("Can we quit?");
        return 0;
}


"Do we quit gtk_main' is printed but not "Can we quit?"
But I guess "Can we quit" has not to be printed.

Also some remarks about how guile scripts are used into drgenius, guile
scripts are embedded into object plugged in a geometric figures logic
and area.
The geometric figures are user interactive, it means guile scripts are
evaluated hundred of time when the user plays interactively with the
figure. Actually I notice, DrGenius may not hang when quitting if the
user just loads a figure (with scripts) then directly quit.

(The following screenshot gives an idea how the scripts are plugged in a
figure http://www.ofset.org/drgenius/sshot4.png )
