Subject: [Bug c/65892] gcc fails to implement N685 aliasing of union members
Date: Sun, 26 Apr 2015 18:00:00 -0000	[thread overview]
Message-ID: <bug-65892-4-VSAhUv7j8d@http.gcc.gnu.org/bugzilla/> (raw)

--- Comment #6 from Martin Sebor <msebor at gcc dot gnu.org> ---
I agree it's subtle and could be clearer but I believe the key phrase is "a
union contains several structures."  Here, the term "union" refers to the type,
not the object.  This is supported by the use of the term "union object" in the
second part of the sentence.

This interpretation is in line with Derek Jones' excellent The New C Standard
-- An Economic and Cultural Commentary: http://www.coding-guidelines.com/cbook

But if there's doubt that this interpretation is intended I'd be happy to raise
an interpretation request on the WG14 mailing list.
