No problem. My initial report was light,  I apologise.

You are right about the stack trace, as it is from the "first known
bad" snapshot, 2011-12-17. And it was wrong of me to use that
snapshot, as the "Bad address" errors don't occur with the latest
snapshot, 2012-01-11.

The crash does not happen immediately, rather after some time,
suggesting to me that find has done quite a number of traversals of
the filesystem before it hits the problem.

I've include output from this one, and attached a cygcheck.out this
time:

And for completeness, here is the output of the same sequence from the
"last known good" snapshot, that I found to be 20111216:
