Right.  So I am assuming that Andrew is using an elfutils which version
is >= 0.165.

Thanks for the insight, Andrew.  I could reproduce the issue now with
elfutils compiled from the master branch of its Git repository.

I need to look at this more closely, but I am guessing that libabigail's
DWARF reader now needs to support the debug informatin entries of tag
DW_TAG_type_unit (that are emitted when the compiler flag
-fdebug-types-section is emitted) which it doesn't support yet.
