EXC_BAD_ACCESS Crash when displaying AdWhirl ad on iPhone

Question

Hi,
I am using AdWhirl in my app and got a suspicious crash mid-game.
It appears to crash in the animationDidStop:finished: function which I didn't create. Could this be a bug in AdWhirl?

I can't find this file referenced in the log:

(MMHTMLAdView.m:123)

This is the log:

Answer 1

Not the answer I was looking for, but decided to dump AdWhirl in favor of AdMob. All the roads to errors were going through uncharted AdWhirl territory so decided to let them figure it out...

Answer 2

I also had many problems with AdWhirl. My last version was ok, the Millennial ad was displayed fine but did not work well when transitioning to iAd. When I tried to make a new version then whenever a new Millennial ad is received the app crashes. After struggling for a while I dumped AdWhirl and wrote my own interface to put a couple of ad networks together and it works without a hitch. So the problem is in the Adwhirl api, not the ad network API.
