Thanks, this is the same issue as your first backtrace.

So now I'm sure that the calls to 'stat' to find out whether files
exist are the culprit, and I hope that due to the changes I made in
the development sources, which avoid calling 'stat' for this purpose,
the next release of Emacs will be free of this problem.

If you can afford it, please try the next development snapshot that
will appear here:

  http://alpha.gnu.org/gnu/emacs/windows/

I will wait for you or someone else to try a recent snapshot and
report the results, before I close the bug.

Thanks again for your efforts in this matter.
