* fix: relocate stack pointer _VAR_sv to keep it alive * fix: add stack pointer _VAR_vk to defend `encoding.TextUnmarshaler` * fix: align faker func's stack with JIT func's * fix: clear _Stack memory when err returned * fix: clear stack pointer before return * fix: relimit stack-overflow check at `_ValueDecoder` Co-authored-by: duanyi.aster <duanyi.aster@bytedance.com>
