--- Comment #3 from Martin Liška <marxin at gcc dot gnu.org> ---
It's the same story we saw for no_stack_protector attribute:

--param stack-clash-protection-guard-size=12 --param
stack-clash-protection-probe-interval=12 + '#pragma GCC optimize 1'

is not equal to:
--param stack-clash-protection-guard-size=12 --param
stack-clash-protection-probe-interval=12 -O1

btw. the default of 16 comes from here:

    { OPT_LEVELS_ALL, OPT__param_stack_clash_protection_guard_size_, NULL,
      DEFAULT_STK_CLASH_GUARD_SIZE == 0 ? 16 : DEFAULT_STK_CLASH_GUARD_SIZE },

and that's why I suggested:

So something for GCC 12. Now let's take a look at the verify_curr_properties.
