There are plenty. What positional disadvantage does in these spots is that it decreases the EV of your play because you're likely to loose more and win less postflop with the worst and best hand respectively or make loads more mistakes. It doesn't however, automatically render any situation -EV, because there could be a bunch of factors that make it +EV so that even with the positional disadvantage it's still +EV, just not as +EV as it would be in position.
Generally due to the disadvantages of playing oop you'll need to compensate for this in order to call, usually by having a large equity edge over your opponents range, or more rarely a skill edge and information as to how you can exploit him frequently postflop (perhaps he stacks off way too light and is a spazz monkey, or always c bets the flop then gives up etc ect) Other factors could be implied odds (being deep enough to flat even oop) or whatever.
To give you an example where your large equity edge makes up enough for positional disadvantage consider the following.
We open AQs to 3bb SB vs BB 123bb deep. Villain is a 23/18 who 3 bets 10% in the BB and is aware you open wide in this position and is therefore light often. He 3 bets to 9bb. Here being oop sucks but so much of his range is air (often dominated air) that our large equity edge vs his range will make calling okay, provided we can play fairly well postflop.
However, consider a spot where our equity edge is smaller. Say we have AJo and open to 3bb MP vs CO and get 3 bet to 9bb. Villain 3 bets 9% from this sort of position so we know we are a slight favourite vs his likely range.
equity win tie pots won pots tied
Hand 0: 51.018% 49.90% 01.12% 1076597544 24110274.00 { AJo }
Hand 1: 48.982% 47.86% 01.12% 1032684948 24110274.00 { TT+, AKs, A7s-A2s, K6s-K2s, J8s, T8s-T7s, 97s+, 86s+, 76s, AKo }
Here's an estimate at a range if he's polarised and 3 betting 9% here. We are doing alright and are certainly slightly ahead. At first glance we may have the equity to flat and IP this could be okay (although not ideal) but here our lack of initiative and our positional disadvantage is going to make it a losing play.
So yeah, while in the AQ example we have a big enough equity edge and are dominating enough of our opponents range etc etc. In the AJ example, althouigh slightly ahead and getting the pot odds to justify a call, if you looked at this spot like a robot and didn't consider other factors, when you weigh in our lack of position/initiative/reads to exploit, it'll be bad to flat.
Calling 3-bets oop sucks, so make sure you've got a damn good reason to do it.
