Compiling sample graphical application, clicking Step into Routine, turning
on Auto Expressions in Watch tab and clicking 11 more times now crashes
estudio.  The line where it crashes is in {EV_APPLICATION_IMP}.make:

   create locale_str.make_from_c ({EV_GTK_EXTERNALS}.gtk_set_locale)

Perhaps the call to te external is the problem.  This seems like a critical bug
since otherwise auto expressions cannot safely be used.
