 Ok, thanks Adrian.

I tried renaming DigiKam's WXMPMeta_RegisterNamespace_1 to
WXMPMeta_RegisterNamespace_1a so that it wouldn't clash with the one in Exiv2.
It now gets a little bit further. Again a SEGV at:

   1073
   1074     _LIBCPP_INLINE_VISIBILITY
   1075     __node_pointer __root() const _NOEXCEPT
-> 1076         {return static_cast<__node_pointer>(__end_node()->__left_);}
   1077
   1078     __node_base_pointer* __root_ptr() const _NOEXCEPT {
   1079         return _VSTD::addressof(__end_node()->__left_);

Backtrace:
