Does HCL Gas Attack copper?

Under normal circumstances copper does not react with HCl, due to the very low reactivity of copper. Hydrogen is never given off. Copper normally only reacts with oxidising acids, such as HNO3.

However, there is a reaction in which copper reacts with concentrated hydrochloric acid in the presence of CuCl2, but I don't think that's what you're after.

Another thing - HCl gas contains no H+ ions, since there's no water present.

Yes, Cu(s) + HCl(g) should make CuCl2 + H2
