--- Comment #10 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- > To be clear: x86/Linux and x86-64/Linux (and for them there is no protection > area during the probing). I misremembered: there is exactly one page of protection area for them because of the way the unwinding mechanism (run on the alternate stack) restores the regular execution of the program.
