Ok, the problem is probably elsewhere.

Yes, this is the last version (ms4w_1.4.0.zip).

I have done many and many tests and I really can't localize the problem.

I have created a dummy driver without any dependencies ( my real driver uses a lot of external static 
libraries and I thank this could be the source of the problem ) and I can't load it.

This really look likes an incompatibility between gdal versions ( basic 1.3.1 and the one used in MS4W ),
for example, in my driver, i do :

   poDriver->pfnOpen   = DUMMYDataset::Open;
   poDriver->pfnCreate = DUMMYDataset::Create;
   poDriver->pfnDelete = DUMMYDataset::Delete;

   int iDummyDriverIndex = GetGDALDriverManager()->RegisterDriver( poDriver );

If i comment the two lines relative to pfnCreate and pfnDelete, i get a different crash. 
It looks like a structure alignment problem or a change in the class definition...

Have you any suggest which could help me to solve my problem ?
