Cross-chaining is bad for your chain and the chain rings - it causes excessive wear, so try not to ride in those combinations. If you're halfway up a hill and it's too late to shift down, it won't destroy the chain immediately, but try to avoid either the big-big combination and the small-small combination.

Agreed, it is possible with a compact double to tune it such that you don't get chain rub in that combo but it's really not good for your chain, cogs etc so it's best if you avoid it.

I meant to also add that in those combinations, you're putting maximum stress on your rear derailleur - it's using every link of your chain, so it has to get out of the way, or it's taking up the maximum amount of excess length in the chain, so it's very easy to damage your RD in these combinations.
