--- Comment #1 from Ivo Raisr <iv...@ivosh.net> ---
The problem is reproducible even with 'none' tool:

$ ./vg-in-place --tool=none helgrind/tests/tc12_rwl_trivial
==29554== Nulgrind, the minimal Valgrind tool
==29554== Copyright (C) 2002-2017, and GNU GPL'd, by Nicholas Nethercote.
==29554== Using Valgrind-3.13.0.SVN and LibVEX; rerun with -h for copyright
info
==29554== Command: helgrind/tests/tc12_rwl_trivial
==29554== 

vex: the `impossible' happened:
   disAMode(x86): not an addr!
vex storage: T total 26363116 bytes allocated
vex storage: P total 384 bytes allocated

valgrind: the 'impossible' happened:
   LibVEX called failure_exit().
