[Dávid Bolvanský via Phabricator via cfe-commits]

xbolva00 added a comment.

  Set current_function_has_unbounded_dynamic_stack_size to 1 when pushing a variable-sized argument onto the stack. 
  
        if (current_function_has_unbounded_dynamic_stack_size)
  	stack_usage_kind = DYNAMIC;
        else
  	stack_usage_kind = DYNAMIC_BOUNDED;

You can compile eg. zstd project with "CC="gcc -fstack-usage" make -j6 -B" and then grep "bounded" . -R and you will find some examples of dynamic,bounded.
