--- Comment #5 from dodji at redhat dot com ---
Thank you for reporting this issue, and sorry for the inconvenience.

Looking at the backtrace it looks like libabigail the segmentation fault is
happening on this line:

=C2=B7=C2=B7if=C2=B7(*l.get_underlying_type()=C2=B7!=3D=C2=B7*r.get_underly=
ing_type())$=20=20


basically, l and r are typdef types.  Normally, {l,r}.get_underlying_type()=
 can
never be NULL, because typedef always have underlying types.

So I am not sure what is happening there.  It would be really helpful if I
could look at the binary itself to see what is happening, but I guess that =
is
not possible, is it?

Just for the record, the git hash I am looking at is this one:
fd8640dc09b99bee11745a4d5b176b2dee3400f4

--=20
