Sure, this is better not to rely on specific options.
Anyway, reduced to:
$ cat ArithmeticSubtermGeneralization.ii
template <class> using no_ref_t = int *;
template <class Arr, template <class> class ref_t>
struct ArrayishObjectIterator {
typedef ref_t<typename Arr::_ElementType> _ElementType;
};
struct MappingIterator {
typedef int *_ElementType;
};
template <class Iter> struct IterTraits {
IterTraits<MappingIterator> map() {}
template <template <class> class Container>
Container<typename Iter::_ElementType> collect();
};
struct Clause {
typedef int _ElementType;
};
IterTraits<ArrayishObjectIterator<Clause, no_ref_t>> __trans_tmp_3;
$ g++ ArithmeticSubtermGeneralization.ii -c -w
hash table checking failed: equal operator returns true for a pair of values
with a different hash value
