[Gdal-dev] Exception thrown in GDALOpen() function

My call to GDALOpen() is now working after having the binaries in debug mode
as my program is in debug mode. I'm opening a tif file and translating it to
erdase imagine for testing purposes (i'm aware that a program already exist
for that operation). I'm kind of exploring GDAL now.
My steps are simple:
- Drivers registration (here tiff and imagine),
All the steps went fine except the last one. The .img file is created and
seems to be ok.
The exception is risen in the cleaning phase. GDALOpenInfo object is being
destructed and an exception is risen when trying to close the .img file.
After a bit of investigation, i found out that .img is opened (in the source
code) using VSIFOpenL function (in the HFAOpen() method), then the file
pointer is passed back to the GDALOpenInfo object.
Once the destructed of GDALOpenInfo is called, the file is being closed
with VSIFClose. In the imagine case the closing would be done using
VSIFCloseL and not VSIFClose. I guess that this is what causing the
exception. It appears that GDALOpenInfo assume that the file is always
opened using VSIFOpen.
