Hi Nick,

I can still reproduce the problem on the latest sources from trunk on Ubuntu
14.04 x86_64.

$ rm test
$ valgrind ld/ld-new -T test
==22837== Memcheck, a memory error detector
==22837== Copyright (C) 2002-2013, and GNU GPL'd, by Julian Seward et al.
==22837== Using Valgrind-3.10.1 and LibVEX; rerun with -h for copyright info
==22837== Command: ld/ld-new -T a
==22837== 
==22837== Invalid read of size 4

Best regards,
