Joaquim,

OK.  Well, generally speaking GDAL should allocate relatively little
memory just on loading the DLL (and perhaps calling GDALAllRegister()).

So I don't know why you are seeing the problem you see.

Frank,
It's ok. I was not expecting an easy answer but I think this issue worth 
reporting.
Anyway, the fragmentation (note that there is not a total free memory 
reduction) is probably
originated by all the gdal.dll dependencies that one can see with the 
Dependency Walker being
loaded by the gdal.dll


Does this aspect really have anything to do with the number of GCPs?
Are you using the GDAL warp algorithm?

Oh yes, with 2500 GCPs I can do the warping. And yes I'm using the
GDAL warp algorithm (the mex is more or less a copy of gdaltransform)

Thanks

Joaquim
