--- Comment #1 from Serhei Makarov <serhei at serhei dot io> ---
This one is worth fixing and dwfltab logic is generally in need of an overhaul
(we are reusing elfutils table code that's barely suited to the task). I
briefly considered implementing the table in C++ but the elfutils library code
(unlike the tools) is not ready for C++ transition.
I'll plan a dwfltab cleanup/overhaul for the autumn elfutils release (i.e.
0.197, not the one this week) and track the work here.
