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

ecstatic-morse commentedon Jan 18, 2022
Looks like a stack overflow in
ty::relate. Needs a call toensure_sufficient_stacksomewhere, probably at the end ofrustc_infer::infer::combine::Generalizer::tysaroundrelate::super_relate_tys, although there might be a better spot. This will have perf implications, however.JohnTitor commentedon Jun 15, 2022
Fixed by #96591, marking as E-needs-test.
