From 354362524a72b3fa43a6c09380b7ae3b2380cbba Mon Sep 17 00:00:00 2001 From: Juergen Ributzka Date: Tue, 19 Nov 2013 00:57:56 +0000 Subject: [weak vtables] Remove a bunch of weak vtables This patch removes most of the trivial cases of weak vtables by pinning them to a single object file. The memory leaks in this version have been fixed. Thanks Alexey for pointing them out.
