commit 58007e9e68913290b1f4f73afc1055f779a8ed5d
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Thu May 28 05:06:27 2015 -0700
Make sure that calloc is called at least once
PLT relocations aren't required when -z now used.
[BZ #18422]
* Makefile ($(objpfx)tst-audit2): Depend on $(libdl).
($(objpfx)tst-audit2.out): Also depend on
$(objpfx)tst-auditmod9b.so.
* elf/tst-audit2.c: Include <dlfcn.h>.
(calloc_called): New.
(calloc): Allow to be called more than once.
(do_test): dllopen/dlclose $ORIGIN/tst-auditmod9b.so.
