RE: [xml] NAN problems on Win32

["Vakoc, Mark" <Mark_Vakoc jdedwards com>]

It is W2K SP2.  The user is an admin.  The more I think about it, I not sure
it's a NAN problem, but some other type of floating point problem.  The
crash occurs when xmlXPathCountFunction calls
xmlXPathNewFloat((double)cur->nodesetval->nodeNr), nodeNr is an int and so
NAN doesn't seem to be dealt with.

The general trend in causing the problem is evaluating and xpath expression
such as 'count(COLSET/*)'.  Problem occurs when there is and is not nodes in
the nodeset returned.

The problem occurs in several other places in libxml, such as the following
crash:

I will do more research and post what I find.  It is difficult because I
cannot duplicate it and I think I am trying my clients patience

Which Windows? Which version?

If Windows is NT or 2k or XP, does the user who runs into trouble have
administrative privileges on her local machine?
