Author: jlh Date: Wed May 16 20:31:37 2012 New Revision: 235520 URL: http://svn.freebsd.org/changeset/base/235520 Log: MFC r235142: Always define LD_32_PRELOAD so it works for 32 bits binaries on 64 bits platforms. Let rtld(1) decide if it needs to honor it or not. While here, fix a small bug in error reporting when asprintf(3) returns an error.
