GNU Attributes like gnu_attribute_alignment not copied by copy constructor and operator==

Hi all,

I found a potential issue that GNU attributes are not copied by the copy constructor and operator=() of classes like SgTypeModifier (e.g. https://github.com/rose-compiler/rose/blob/weekly/src/ROSETTA/Grammar/Support.code). Because of that, those attributes will get lost on copying.

Is this intended or a bug that can be fixed?

Thanks!

Read src/ROSETTA/Grammar/Support.code and inspect how classes such as SgTypeModifier implement their copy constructor, operator=(), and operator==(). Trace how GNU attributes such as gnu_attribute_alignment are represented, then verify that copying and equality preserve them; the issue provides no test location, so a suitable regression test would need to be identified.
