Unfortunately the minimal failing test is a bit complicated I'm afraid, this only seems to show up with a hierarchy of serialization classes. I've attached valgrind memory testing output which should hopefully give all the clues needed to track it down: {{{ ==20488== Memcheck, a memory error detector ==20488== Copyright (C) 2002-2013, and GNU GPL'd, by Julian Seward et al. ==20488== Using Valgrind-3.10.1 and LibVEX; rerun with -h for copyright info ==20488== Command: mesh/build/debug_hostconfig,boost=1-65/TestNodesOnlyMeshRunner -malloc_debug -malloc_dump -memory_info ==20488== Parent PID: 20487 ==20488== ==20488== Invalid read of size 8 ==20488== at 0x7E55025: boost::serialization::typeid_system::extended_type_info_typeid_0::type_unregister() (in /home/robert/boost_1_65/lib/libboost_serialization.so.1.65.0) ==20488== by 0x4756E6: boost::serialization::extended_type_info_typeid >::~extended_type_info_typeid() (extended_type_info_typeid.hpp:96) ==20488== by 0x474F02: boost::serialization::singleton > >::get_instance()::singleton_wrapper::~singleton_wrapper() (in /home/garmir/workspace/Chaste/mesh/build/debug_hostconfig,boost=1-65/TestNodesOnlyMeshRunner) ==20488== by 0x9E2E1A8: __run_exit_handlers (exit.c:82) ==20488== by 0x9E2E1F4: exit (exit.c:104) ==20488== by 0x9E13F4B: (below main) (libc-start.c:321) ==20488== Address 0x17bd1740 is 32 bytes inside a block of size 40 free'd ==20488== at 0x4C2C2BC: operator delete(void*) (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==20488== by 0x7E55572: boost::serialization::singleton > >::get_instance()::singleton_wrapper::~singleton_wrapper() (in /home/robert/boost_1_65/lib/libboost_serialization.so.1.65.0) ==20488== by 0x9E2E539: __cxa_finalize (cxa_finalize.c:56) ==20488== by 0x7E4D402: ???
