this equates to -ftrivial-auto-var-init=pattern clang has removed support for -ftrivial-auto-var-init=zero and are unlikely to re-add it, so use -ftrivial-auto-var-init=pattern on both compilers if only to make behaviour more consistent between the two. add to pkgsExtraHardening's defaultHardeningFlags.
