Lennart, could you please explain in plain English what is the
problem?  I'm sorry, but I cannot make heads or tails out of the
original report you cited, nor can I understand the precise recipe to
reproduce the bug.  Is the reason the non-ASCII characters used in the
value of HOME? or is that the symptom of corruption? what does probing
C:\.emacs have to do with this? etc., etc.

Since you say that you can reproduce the problem with a fairly recent
build, please give a precise recipe for that, including what should be
the value of HOME, which .emacs files should be present in what
directories, etc.

And please don't use NTFILMON or similar tracing tools; instead, if
you need to see what is going on under the hood, please step with a
debugger into the relevant code (it's in the function init_environment
defined on w32.c), and tell what you see.

Thanks.
