I wonder which other opclasses besides ltree have the same issue.
I found no other similar places: siglen is also accepted by opclasses
gist__intbig_ops, gist_hstore_ops, gist_trgm_ops, tsvector_ops,
which implementations use functions
_intbig_alloc, ghstore_alloc, gtrgm_alloc, gtsvector_alloc,
and none of them adds siglen to a pointer.
Quick testing confirms that.
(gist__ltree_ops uses ltree_gist_alloc(), but the problematic branch
"if (left) ..." not reached for gist__ltree_ops)
