Yes, you've posted it multiple times and I've never heard that anyone besides
you has had this problem.

The error is occurring in a system DLL.  The exception is not in a standard target
exception format.

That actually points to a problem in Windows NT.

Out of curiousity, have you ever just typed "continue" at this point to see if
things progress normally?

From John Peacock's stack trace for his failing situation, it seems like the specific
function that is failing is NetUserGetInfo.  Specifically, line 92 in uinfo.cc:

      if (!NetUserGetInfo (NULL, wuser, 3, (LPBYTE *)&ui)
          || (wlogsrv[0] && !NetUserGetInfo (wlogsrv, wuser, 3,(LPBYTE *)&ui)))

I don't see anything in this code that would cause this type of error, though.
In fact, I wouldn't expect NetUserGetInfo to ever cause a segv.  That's why I
suspect a Windows bug.

Maybe somebody might want to inspect the Microsoft MSDN and see if there are
any caveats about this function.
