Summary: Crash when tclWinProcs->getFileAttributesExProc is NULL

Initial Comment:

Running a FCMD_EXISTS in Tcl_FileObjCmd:

If tclWinProcs->getFileAttributesExProc is NULL then
the  following line in TclpObjNormalizePath will fail:

if ((*tclWinProcs->getFileAttributesExProc)(nativePath,
		    GetFileExInfoStandard, &data) != TRUE) {
		
On my Windows 2000 system, this function pointer is
always NULL at the point of failure. 

TclWinSetInterfaces (being the only function I can find
that sets this up) doesn't appear to have been called
at this point.

Please ignore the multiple comments - problems with the

The problem appeared after trying to upgrade the TCL library
from 8.2 to 8.4. I wasn't involved in the original
implementation of our product, so I know little about the
history.

Obviously, I am missing some initialization step that was
either added since 8.2 or is a little more critical now.
I'll check the docs and source code. 

You can close this if you like.

The test suite works OK. 

We have the TCL library embedded in our C/C++ application.

You'll have to provide a test script or more detail as to
how you are using Tcl, since this works for me.

Have you tried running Tcl's test suite?

Vince.
