I was poking around this last week with the type identification. C frontend
seems
always make the type complete by copying the fields in c-decl.c:finish_struct.
I tried to add check that types are complete when main variant is and learnt
that
C++ FE seems in some cases leave the type incomplete even if main variant is
complete
but not in such a simple cases. I will look into it a bit more after arrival -
but
that is my recollection. The finish_builtin_struct was only case where we set
DECL_SIZE but not DECL_FIELDS
