[gdal-dev] Setting "INIT_DEST" to nan on windows

I did have to set the padfNoDataImag array as well, so I am one step
closer.  My new issue is ownership of my psWarpOptions.  I assume that since
I create it, and the warp api tutorial implies that is it mine, I destroy it
with GDALDestroyWarpOptions().  My problem is that AutoCreateWarpedVRT
appears to be stepping on my warp options when it destroys it's own copy.

I call AutoCreateWarpedVRT() and that function calls
GDALCloneWarpOptions().  When AutoCreateWarpedVRT destroys the copy it owns,
it appears to be stepping on my copy, and when I call
GDALDestroyWarpOptions(), I get a seg fault.  Am I doing something wrong?
