this is not exactly ICE, but I did not find an appropriate variant for this

Looks like a stack overflow in ty::relate. Needs a call to ensure_sufficient_stack somewhere, probably at the end of rustc_infer::infer::combine::Generalizer::tys around relate::super_relate_tys, although there might be a better spot. This will have perf implications, however.
