From 3a05767c2bbba5ee75c9adf0a5971258405520a8 Mon Sep 17 00:00:00 2001

Subject: [PATCH] GCC: workaround constexpr and raw_ptr issues in autofill
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
First, we workaround the problem with some constexpr destructors
declared to use default implementation, that are not properly
resolved when used.
Then, apparently GCC cannot resolve raw_ptr to a constexpr.
