I'm still not sure whats causing it, but I was deserializing a basic
json object within a thread, and today - and ONLY today - I've been
getting the stack dump below. If I do it outside of a thread, it works
_fine_.
Anyone else seeing this?
XC 4.3.1
iOS 5.1
MT latest beta (installed this morning)
I tried going back to an old MT (5.2.5) with the same result. Once I
get this, if I restart my app, I get seg faults in all the codes....
mostly sqlite.
Very odd.
