In a multiply-corrupted DWARF object libdwarf may try to dealloc(free) an allocation twice.
Results are unpredictable and various. This has been a possibility since we added code to prevent leaks when generating 'unattached' Dwarf_Error records (where there is no Dwarf_Debug available at the point of error).
The problem was introduced in libdwarf-0.1.0 in 2021.
