I think this is a pretty easy call. First, 4 ways we have an equity edge (slight though it may be).

There are 3 problems as I see it:
1) Someone has a set and therefore your equity drops because of the chances of them filling up. This doesn't concern me as much because with so many other players raising, I assume that some of their pairing outs are being held by other players.
2) You are drawing to a split. Quite possible, but no real reason to fear that yet. As it is, someone could conceivable be drawing to a worse straight. Anyway, maybe discount a little for that but no reason to worry yet.
3) This crap is going to keep going on the turn, and make seeing the river very expensive. Two things mitigate this somewhat: 1) with this much strength, people are probably going to calm down on the turn unless we've got set over set, and 2) if it is likely to go nuts again on the turn, you're looking at nice implied odds if you hit.

So I think we definetly call here for those reasons.
