Subject: [Bug c++/23643] Incorrect conversion from derived to empty base class
Date: Fri, 12 Jan 2007 08:18:00 -0000 [thread overview]
Message-ID: <20070112081840.6017.qmail@sourceware.org> (raw)
In-Reply-To: <bug-23643-11269@http.gcc.gnu.org/bugzilla/>
------- Comment #3 from jbuck at gcc dot gnu dot org 2007-01-12 08:18 -------
Andrew is right, this isn't a bug, and is in fact required by the ABI.
See http://www.codesourcery.com/cxx-abi/abi.html#class-types, section II,
subsection 3. "First, attempt to place D at offset 0." No rule prevents doing
this, so that is where it lands.
