There is no panic. The program starts complaining about the 
account data that it is checking, spewing bogus error messages. 
This is because the Account structures have been zeroed at some 
point in the recursive descent.

But I did set a breakpoint in gdb at the place where the error 
messages are issued, and i was something like 230 of an 
n_children of something like 350. I don't think either number is 
particularly significant, other than that this was an account 
that had a lot of children and so was likely to trigger a gc.
