From ef4f97648dc95849e417dd3e6328165de4c22185 Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Fri, 26 Aug 2016 22:40:27 +0200 Subject: malloc: Simplify static malloc interposition [BZ #20432] Existing interposed mallocs do not define the glibc-internal fork callbacks (and they should not), so statically interposed mallocs lead to link failures because the strong reference from fork pulls in glibc's malloc, resulting in multiple definitions of malloc-related symbols. --- malloc/tst-interpose-thread.c | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) create mode 100644 malloc/tst-interpose-thread.c (limited to 'malloc/tst-interpose-thread.c') diff --git a/malloc/tst-interpose-thread.c b/malloc/tst-interpose-thread.c new file mode 100644 index 0000000000..d3e20c7457 --- /dev/null +++ b/malloc/tst-interpose-thread.c @@ -0,0 +1,20 @@ +/* Malloc interposition test, dynamically-linked version with threads. + Copyright (C) 2016 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public License as + published by the Free Software Foundation; either version 2.1 of the + License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
