--- Comment #1 from Alexandre Oliva <aoliva at gcc dot gnu.org> ---
Eric, I think this is yours.
It fails while trying to add a reversed version of the hbool type to the
context of the struct, but the struct doesn't have children yet, and
add_child_die_after requires the context to have children already. The
assumption that the original, unreversed type was introduced in the same
context doesn't hold.

This works with __attribute__((may_alias)) though, so what's special with
__attribute__((__hardbool__)) ?

Replying myself: this creates an enumeration type under the hood, so this is a
duplicate of PR debug/113519.
